So you mean exchanges like Coinbase and Binance? What other exchanges are there for this that you recommend?
How do you exactly calculate all the fees so you know exactly how much profit you turn?
I think there is no recommended site to arbitrage.
Because every exchanges have different price on different coin. So you better have account on many exchange and find out what exchanges best.
Personally, I still not doing arbitrage but I have some exchange account which give me knowledge about different price.
