I study chart analysis, every day. Open salt of trading view, open the "accumulation / distribution", notice the irregularity.
As the price is going down, accumulation is increasing, My analysis concluded that there is a group or a person accumulating a ton of salt for some reason. People see this coming. By this I mean the imminent pump.
Happy trading! Source (book):A Complete Guide To Volume Price Analysis
The transaction fee on binance is 0.1% or 0.05% if you use bnb to pay for fees. On bittrex is 0.25%. On binance this is the market: https://www.binance.com/trade.html?symbol=SALT_ETH
and on bittrex: https://bittrex.com/Market/Index?MarketName=ETH-SALT
Transaction fee only depends on the amount you are exchanging. It's probably better to buy it using BTC as it has more volume, and when the volume is higher, the spread is lower. You lose less buying and selling at marketprice because the difference between buy/sell rates is lower. But you can check that yourself. I think probably it's full of bots trading ETH markets gaining with those edges :P
SALT is a ERC20 Token so it can be stored on your Ledger. Install the Ethereum app and you're good to go. Personally I use a mobile version of MyEtherWallet. It works smooth and got no issues.
I'll share it with you here, cause it's temporarly not available on the PlayStore unfortunately: https://jumpshare.com/v/0vdkxlndOWq5CdTQjzju
Have fun!
