This guide is pretty good, but if you don't have the time or if it's too technical I would recommend getting a hardware wallet. Airgapped just means no internet connection.

But basically it follows these steps:

• Use old PC if you have one or boot OS (like Tails) from USB drive
• Make sure to disable all internet connectivity
• Download MEW from github and use it to create a wallet (MEW can be used offline)
• Print the wallet on a secure printer, preferable if it isn't a printer that can connect to the internet, also possible to just write down your private key by hand (which can lead to errors)
• make sure to NEVER connect the PC/OS you created your wallet on to the internet
• optimal: save the keystore file from MEW on a USB stick, don't connect that USB stick to a PC with internet connection

This article is okay.. The "wallet" term means different things to different people, and I don't love the use of it here. People really need to understand that private keys are the fundamental point of control, and wallets are simply address managers, not something you ever need to have. I much prefer how I explained different wallet types in my old post here.

Depending on the amount you're holding, how you intend to use the funds, the risk you're willing to incur, and the amount of time/effort/money you're willing to put into things, there are a lot of possible wallets that could be right for you.

I'd really recommend you read part 2 of my crypto security guide which focuses on wallet analysis.

I'd be happy to help you figure out the best way to store your crypto if you can describe your use case a bit. Simply saying "use X site" or "just buy Y" is not advice you should follow blindly on recommendation alone.

IMO, Ethereum isn't going to rise significantly on august 1. It will likely even dip some as people move into BTC in the hopes that scaling issues are being resolved. Before august 1, a lot of funds will move to BTC in order to support the BCC fork which many (incorrectly) see as free money.

You're mistaken to think that there is any giveaway related to Ethereum.

Ethereum is different from Bitcoin in many ways. For more info on gas, I'm just going to link you to this post I wrote, but you can ask me questions if you have any.

Just understanding gas isn't going to get you super far in terms of all the differences between BTC and ETH. This is great for understanding the basics of cryptocurrencies.

Once you have a solid grasp on things like blockchain, consensus algorithms (like PoW and PoS), and how mining works (from the network perspective, not how to mine), then you can start looking into Ethereum-specific topics like smart contracts. I really don't have all weekend to write a good comment on all of these, but there are great guides out there already and hopefully you know what to look for now.

See trading & market analysis section. Dalin from High Altitude Investing is consistently doing very well and his approach simply works. I take fundamentals/news into account more than he does, but his TA is generally very solid.

If you are looking for the mobile wallet then definitely Trust Wallet. It is available for both iOS and Android, has support for any ERC20 compatible token (autodetect all the tokens) and ERC721 collectables.

Also includes Web3 dApp Browser to access decentralized exchanges and blockchain games, that's like Meta Mask on mobile.

More details on https://trustwalletapp.com

If you plan on being an active trader you need to have very low transaction fees. Binance introduced a 50% off of fees IF you have enough BNB (Binance Coin) to pay for the fees. To incorporate what I just mentioned and keeping with the spirit that ETH is king; day trade the pair BNB/ETH.

Then take your profits to fund your long term positions on the list you have. Do not day trade those coins on the list. Instead equal weight them once a month. For example, if you have 3 coins on your list you'd like to see grow over a few months. Spread 33.3% of your long term list allocated value to those 3 coins. Like you mentioned about when to buy high or low....when you rebalance the 33.3%, it will do two things for you:

• Preserve your value inside your portfolio instead of bleeding out value
• Automatically it will buy the lowest performer and sell the highest performer in your list (buy low, sell high)
  

Good luck and see you on the battlefield.

If you take a look at this screenshot from cryptowatch.com, a free website that provides charts for various crypto currencies, you can see what's known as the order book on the right side.

Basically you see all the sell (ask) orders in red and the buy (bid) orders in green. It shows how much ETH (in this specific case) are being asked/offered at a given price.

For example, in the screenshot you can see that at a price of €180.0000 there are 459.142ETH for sale. And at a price of €179.60001 there are orders to buy 227.417ETH

People speak of a sell wall if there are high amounts of ETH for sale at various prices. Say 800ETH at €181 and 1700ETH at €182 and 2300ETH at €183....

Hope this helps.

If you're technically inclined, I wrote a 3-part security guide that covers almost everything involved with deciding on and implementing a crypto security system.

Part 3 dives into creating your own air-gapped system and addresses a lot of the issues hardware wallets overlook.

Ah okay. My Ethereum "Gas" - How it Works blog post is a popular introduction to the function of Gas.

Vitalik's Ethereum in 25 Minutes is a great introduction to the platform as a whole (he did a new version of this more recently at Devcon3, but I can't seem to find the video/timestamp).

What type of security are you trying to focus on? Ones I can think of off the top of my head could be:

• Blockchain security (how miners ensure the blockchain is immutable) • Transaction security (how public key cryptography is utilized to verify transactions) • Address security (how there is no way to brute force into an address, no possibility for a backdoor, no way for regulation/external control by anybody) • Network security (how decentralization guarantees 100% uptime, fights against DDoS)

There's also user-level security like how you store your crypto. I talk about this type some on my Steemit blog at https://steemit.com/@tomshwom.

For using an exchange, a new computer isn't super necessary if you are using two-factor authentication (using google authenticator, not SMS). Use a strong password, log out after you're done using it. You want to use google authenticator over SMS because it's possible to intercept SMS messages through SIM card spoofing, but any 2FA is better than none.

For using a wallet application, it really depends. There's no point in buying a new system if you're going to store $20 of crypto on it, just like you'd be a moron for storing $20k on your main desktop. There's a lot of options when it comes to keeping your crypto safe, but the easiest ways (online/software wallets) are often the least secure. Safer ways (hardware wallets) are a bit more expensive and less convenient, but are still easy to use. The safest ways can be a bit technically challenging, but don't have to cost much at all.

The best thing to do is match your storage solution to the level of convenience you will want for your funds. If you are a trader, you're not going to want to use a convoluted security system every time you want to make a trade, and more likely than not you will stop using it altogether. If you're just accumulating for the long-run, then having a very secure storage solution is a good idea, even if withdrawing from it is a bit of a pain.

Feel free to comment/message me if you want any specific info about wallets/security. You can also check out my Steemit page for a variety of crypto security/hardware/tutorial/investment content.

Link is embedded in "part 1", but here it is: https://steemit.com/bitcoin/@tomshwom/tomshwom-s-advanced-crypto-security-guide-part-1-privacy-security-and-trust.

I'm not really sure what you're asking by "is that ok?". It sounds like you're using an online wallet, which is as "ok" as you decide it to be really. On the wide spectrum of security, it's definitely not on the very secure side, but it's unlikely that you're at immediate risk of losing your funds.

Yeah try to get that GDAX account so you can buy/sell with 0 fees. You could also look into other ways to buy on Coinbase.

If I buy with a credit/debit card, I get my coins instantly at a 7% fee or whatever it is. If I buy with my bank account, it takes ~5 business days to get my coins, but it is only a 1.5% fee.

Another option: check out Changelly. It's a 3rd party service. You'll get your coins in 5-30min and there's a 0.5% fee. You will need an Ethereum address to receive the coins (your Coinbase one, MyEtherWallet, etc)

It depends on what you want to use it for. If you're looking for a wallet to do daily interactions with decentralized applications, you should go with Metamask. If you're looking for cold storage to just store your crypto, you should use MyCrypto ;-D. If you have a lot of money in crypto, i would recommend getting a hardware wallet (Ledger, probably). You can use this with both Metamask and MyCrypto.

Sorry if this seems low-effort, but I'd really just recommend you read this blog post I made a while back.

Hmm.. I'm going to suggest you read through my 3-part security guide that starts here. Even if you just skim through it, I think it will be valuable information to help you decide the route you want to go. Part 3 may be particularly useful if you decide to go with a high-security option that doesn't cost much (but requires a tiny bit of work to set up).

Let me know if something in there sounds like it's what you're interested in, and we can work from there.

I'd really just recommend reading this blog post I made several months back. If you still have questions, feel free to drop 'em by.

https://steemit.com/ethereum/@tomshwom/ethereum-gas-how-it-works

I use excel. Wrote a tutorial for importing live prices from Coinmarketcap and Coincap.io you can find here. Did a similar post for google sheets here.

I just like the ability to create any kind of graph, sorting, projection info, etc. that using your own spreadsheet provides. Definitely some work to get right though.

Poloniex was the one I used to trade most alt coins on. Check the markets tab on coinmarketcap -> https://coinmarketcap.com/currencies/ethereum/#markets to see where most people are trading a coin.

Firstly, do you want to be running a node? There's no need to download the blockchain unless you want to be mining or running a node. If the answer is no, then you can still use the address you already generated with Parity on something like MyEtherWallet, but you don't need to be running the Parity client.

If you do want to be running a node, then there's many ways to prune down the storage requirements and speed things up.

As far as exchanges go, you do not control the address on these websites. You won't get the private key, thus you can never transfer the funds yourself manually. However, it's very simple to buy on an exchange (where it's held by the exchange address) and then transfer off to an address that you control.

Side note: it's good that you've backed up your recovery seed and private key on an offline device, but you will want to make at least one extra copy for redundancy. Also, from a security perspective, there's not a lot of difference between storing this information on the computer if you're going to plug the drive into it anyways when you use it. A keylogger/clipboard sniffer is going to get it regardless, and that's going to be the primary attack vector for stealing private keys aside from scams/phishing. Look into hardware wallets if you're planning on holding any significant amount of crypto, or if you're tech savvy, check out this guide I wrote on creating something like a hardware wallet on your own.

My standards for security are probably much higher than most people. The majority of my holdings are stored in the system I outline in part 3 of my guide here. The rest are stored on GDAX mostly.

I like GDAX because they don't have maker fees, but some people prefer other exchanges.

From a totally paranoid and overly cautious security perspective, you should think about the following:

• Has my private key ever been displayed, stored (unencrypted), typed, copied on the clipboard, or otherwise "on" a system that is connected to the internet? If yes -> potentially compromised.

• Has my private key ever been stored in a location accessible by people other than trusted parties? If yes -> potentially compromised.

So in your case, it is possible that one could retrieve your private key from the printers memory or through sniffing network traffic. This may or may not require physical access to the network/systems.

Something more likely is to have malware that is sniffing clipboard contents and keylogging you. If you generated your private key on an online system, then when you copied / typed it to the document for printing it could've been picked up.

Also, anytime you use your paper wallet to sign a transaction, if you're doing that on an online system you are negating all of the security provided by a good offline private key storage system like a paper wallet.

Something else that people don't think about a lot is that digital security is often easier than physical security. When you print your wallet info, you need to keep redundant secure backups of it. Say your house burns down, is broken into, or your kid/dog is just curious about what's in that upper drawer... You could store it in a safety deposit box at a bank, but that's also not a fullproof solution depending on your needs.

If you like the mental exercise of thinking about wallet security, I'd recommend starting with part 1 of my security guide, and continue through part 2. Part 3 is an actual guide for creating a wallet that I consider to be very secure and not too difficult.

They may be slightly different in the info they store. Try scanning them with a QR code reading app on a phone and see if they contain correct information.

Also, while I'm here, I suggest you create the MEW stuff on an offline / air-gapped, secure system. The purpose of having a paper wallet is so that your private key (or keystore file + password) never, ever, touch a system that is or ever will be connected to the internet. This goes for printers as well since they are generally connected to the internet and have memory of the jobs they print.

There's varying levels of security to consider, and worrying that your printer is compromised and somebody is snooping through your network traffic is probably a bit over-protective for most people. Still, if you're trying to make an extremely secure wallet for cold storage, there's extra measures you should take to avoid all conceivable flaws.

MEW has a lot of helpful resources at https://myetherwallet.groovehq.com/help_center.

If you look into the "How do I use MEW for cold storage" section, you will find the guide I wrote on how to create a secure bootable USB that contains your offline MEW files and other important things.

Whether you go this route or not, feel free to let me know if you have any problems or questions about creating a secure wallet.

See part2 and part 3 of my guide on this topic. Part 2 explains the pros & cons of different wallets, part 3 is a guide for creating an extremely secure wallet. You may even want to check out the very first part because it talks in depth about privacy and security in a more general sense.

Maybe check out my list here to expand things. I have other guides/analysis pieces too that may be of value individually, but I'm probably not consistent enough to be a source myself.

Yep I signed up at Kraken now, like you many people talk very positive about them, thanks for confirming my decision. It took them awfully long to verify my account information (am from germany so I have to be verification Tier 3 to deposit fiat), but now they finally approved and I made a deposit - waiting for it to be cleared. I agree the charts at trade.kraken.com are indeed very nice but it was not a selling point because you have the same thing at cryptowat.ch check it out ;)

This article is pretty good for getting started. Or you can follow this "Hello world" example.

In terms of languages, the CLI has a few depending on what languages you are comfortable with. Such as Pyethapp (Python), Geth (Go), Parity (Rust), ethereum-haskell (if you are into functional programming).

Thanks a lot! That Tor bug is really crappy, and finding older versions of Tails is a bit tricky :/

You might try downloading a portable browser, putting that inside the persistent volume, and using it to open the MEW client. https://portableapps.com/apps/internet would be where I'd start looking for portable browsers.

This article is really about blockchain size, but does a really good job of explaining the different types of nodes at a high and technical level.

> For now I think it would be even harmful to have everything over TOR

Yes and no. Tor can be a red flag for people already monitoring you, but it's also pretty secure as long as you're using it properly. Google around for "how to securely use Tor" and see what you can find. It's amazing how little things like your browser window size can de-anonymize you.

An alternative would be to use a VPN like Private Internet Access (which is more or less proven to not store logs).

Projects like Mysterium Network may be of interest too, though I don't think it's in a usable state yet.

> I feel that my security / privacy are more than enough to not attract attention (and not give away any evidence) at the moment - do you agree with that?

From what I can tell, I'd agree with that.

you can stake that amount on this pancakeswap new staking tool , check app here on play store if interested : https://play.google.com/store/apps/details?id=com.protocol.cakeunstaketool

you can stake ethereum in this app which was released recently, just connect your wallet and stake desired amount ,as easy as that , check app here on google playstore https://play.google.com/store/apps/details?id=com.protocol.ethereumpos

Is this post really removed ? Looks interesting !
May I share with you one of our articles that talks about it, hope it helps :)

This book could help you out. Programmers guide to ETH 👍

Mastering Ethereum: Building Smart Contracts and DApps https://www.amazon.com/dp/1491971940/ref=cm_sw_r_cp_api_i_CW2V8AVYGT301NCXX4TG?_encoding=UTF8&psc=1

There are many apps that can help you with finding alt projects to add to your portfolio. However, recently launched projects are difficult to estimate because these apps handle rough data rather than every minor detail of the coin, mostly based on the market’s readings.
For example, I use SupraFin to look for other projects. The app reads the market and suggests which coins you should buy by taking into account a profile risk you set. I really recommend the app for people that don’t have enough time to study the market on a regular basis. Here’s the iOS version.
After that, I do some research about the suggested coins and examine whether I should invest in them or not. As a rule of thumb, if I want to trade, I’ll look for volatile coins, but if I want to hold for some time, I look for stable coins with a promising schedule.
It’s very hard to amass such an immense amount of information on one tool, so you’ll have to put some effort into it. Fortunately, there are many discord servers and forums in which you can discuss new projects. Just ask away! Most people like giving a helping hand.

There is a OMG/USD pair on Bitfinex, check it out here : https://coinmarketcap.com/assets/omisego/#markets

For OMG/USD it's on Bitfinex but for ETH/OMG, you're right it's may be better to use Bittrex !

Multi-sig wallets are not good for 2FA. The information needed is not dissimilar, and it's up to the user to handle the information in different ways. These are the first rules of good multi-factor authentication, the multiple factors actually need to be very different from eachother.

If you want a simple multi-factor setup, get familiar with KeePass and create a password database that uses a password + keyfile. Store the keyfile on a separate device, and commit the password to memory. Now you need something you know + something you have to access the information. I wrote a comprehensive guide to KeePass that you can find here if you want a detailed look at the software.

Haven't heard of it, but I'm also completely uninterested in Android/iOS wallets since they are all inherently insecure.

What sort of use-case are you looking at? There may be good ways to achieve what you're looking for without extra software.

Go to :https://coinmarketcap.com

Select whichever coin you're interested in and click on the "market" tab. A list of different platforms which offers the coin you want will be listed. Hope this helps.

A useful reference is to compare the ROI of a token to ROI of ETH. Have a look at icostats.com. Of the 30 tokens studied, only 11 have outperformed ETH since their launch. Vast majority of tokens fade into illiquid obscurity within months of crowdsale (check out https://coinmarketcap.com/assets/views/all/). Lots of scams. To date best bet by a million miles is holding ETH. I'm a noobie to cryptos too but my background is in investment management and I know that I wouldn't touch 99% of these tokens with a bargepole....

Can I ask you something ? I wanted to buy some BTC (a small amount for testing purposes and then dollar cost average). I installed an Electrum wallet and the exchange I picked was Changelly, because their rates are average I think. I didn't buy anything because I wasn't too confident so I kept reading about Bitcoin instead.

That's when I found out about Bitcoin Cash, which I'm more interested in than Bitcoin. So I started reading about Bitcoin Cash and came across this. I uninstalled my Electrum wallet already but does it mean I'm really taking a risk by installing Electron Cash on the same machine, even if my Electrum wallet's been uninstalled ?

Also, I think I can buy Bitcoin Cash with FIAT via Changelly but I heard I should buy Bitcoin and then trade it against BCC. Is that true ?

Here is a blog i wrote about gas that you may find helpful.

But to answer things here, your 21k gas limit is good for sending to coinbase. If you specified a lower gas price then you have waited some time before the transaction was included in a block. Now you are waiting for 25 additional blocks to be mined in order to "confirm" your transaction. Each block takes around 15 seconds usually, but heavy load could change that.

You just have to wait it out. If you did screw up, and you specified too little for the gas limit then you would get an out of gas error and the transaction would fail. In that case, you would lose some fees to the used gas, but your funds would have never left your address as far as the blockchain is concerned.

Saying > am I screwed because the ETH is just stuck on the blockchain

indicates to me that you don't quite understand how the blockchain works. Everyone's balance is determined by the blockchain. It's not a vehicle for transactions, it's a state machine that describes the current balance of everyone's wallets. Transactions are handled by the miners and reflected in an updated state of the blockchain.

Nothing changed. This was the plan all along. Layer 1 ETH was always supposed to be very expensive because maintaining an extremely high level of decentralization and security costs a ton of money. The plan has always been to get retail onto Layer 2, and that is finally being rolled out and those systems configured.

You got in early. You got in at a point when there were so little people using Mainnet Ethereum that you were able to complete operations that will eventually cost hundereds and thousands of dollars. L1 is not getting cheaper. The devs have been thinking ahead which is why Layer 2 solutions have been in the pipeline for YEARS.

Vitalik's vision of insanely cheap decentralization is finally coming true. Depending on what layer 2 dapp you use, you can make very cheap transactions.

L1 is designed to get more expensive as it grows.

L2 is designed to get cheaper as it grows.

Essential reading on the Ethereum Roadmap

I haven't tried Exodus myself, but just throwing in another option: You might wanna try Jaxx. It has a web version as well as mobile apps for iOS and Android. Jaxx supports a multitude of assets. It is useful for smaller amounts that you use on a day-to-day basis. I've been using Jaxx and find it very convenient.

If you've got any larger amounts that you just want to store (as opposed to actually spend), the use a paper wallet generated by My Ether Wallet.

It might be easier (depending on where you live and services you have available) to buy bitcoin and trade it for ether, but both buying bitcoin and exchanging for ether will include fees, so compare it to buying ether directly first.

Really simple to do it in the Jaxx wallet because it it has ShapeShift (an exchange) integrated, and Jaxx is on all platforms and really simple to use.

Just create a wallet, make a backup by writing down your 12 words and store them safe on paper.

What you want to do with them is up to you, but you can now send them to whatever adress and brag about being part of the #CryptoMasterRace.

Ethereum is so much more than just a store of value though, so if you want to get into the tech then let me share this reading list.

/u/druikgewak, the only ETC address you can see in the app is a smart address for exchanges provided by our partner, Changelly.com. If you sent your ETH there, we'll be able to contact them and request to retrieve the funds. Our support team will keep you posted.

Edit: ~~Hardware wallet is the simplest option.~~ Just noticed you have one en route!

 

Otherwise, creating a cold storage wallet on an air-gapped machine.

 

W/r/t using MEW without compromising your private key, install MetaMask and use that to interact with MEW instead.

"from Asia" is way too broad to say much..

You can see who Coinbase serves here, and Kraken here (ctrl+f search for "countries").

Again, what methods are you using to come up with these numbers?

There are many things that lead to price discrepancy like this. The first is fiat transfer fees. Exchanges often charge a flat percent fee for fiat transfers. Market orders also incur larger fees since they take liquidity out of the order book.

If you're using Kraken as your baseline, look at https://www.kraken.com/help/fees and see if anything here accounts for the difference you're observing.

The thing I really like with ethereum is you can play around with it a lot which is great for learning, although it often just results in more questions!

Try creating a token on the test net as a good start, your own personal ICO: https://www.ethereum.org/token

Hey there!

First of all congrats to you! You must be excited.

In terms of claiming you ether, I suggest you download the Ethereum Wallet app from the ethereum organisation's website here.

While downloading the app and installing is quick, you'll have to download the entire Ethereum blockchain. This might take days and is currently about 40gb or so large.

When that's done though, you can easily import your pre-sale wallet via Accounts>Import accounts. That's where you drop your pre-sale wallet.

You can then create more accounts in the app to move your ether if you wish.

You might also want to open an account with an exchange. That's where you'll be able to sell ETH and withdraw. I can recommend Kraken but others might be better depending on where you're based.

Hope this helps!

JSON is a way of storing objects in human-readable text. Use accounts > backup to export your wallet JSON file from your Ethereum wallet, and do the same to import it.

I just wrote that, does this help?
