Do any of you have personal experience doing this?
Yes.
What platform are you using?
Luno and bittrex
Is it worth trying out to supplement your income?
Depends on the amount of money you arb with. a few million? yes. 1k? no.
How much money can you realistically make by using the minimum R100k investment? The platforms that offer this paint very rosy pictures of the potential returns but it would be nice to hear someone’s personal experience.
currently if you arb between BTC USD on kraken and BTC ZAR on luno you will loose money. As with everything its not a given. See https://cryptowat.ch/home where you can compare Luno to other exchanges.
Also. A platform? what platform? Be VERY careful of "platforms" that do this. Remember as soon as you transfer crypto so someone its gone. There is no fraud department that you can phone and get your money back. Scams are wild in crypto
Are there any risks associated with doing this?
Much, Crypto can move by 30% in 10 minutes. You can loose thousands while you're sleeping. Not only that its now illegal to transfer without notifying SARS / SARB first.
Would you recommend crypto arbitrage to your friends and family?
