Hi guys!
I just learned that it is possible to make good money using CC arbitrage.
Example: Buy on EXMO 0.1BTC for $100, Sell on Poloniex for $120. Profit $20.
I read a lot about this, but just found out this forum and maybe you can help me.
I can't find any normal trading platform because there is no difference in price at all. The all approximately sell and buy at the same price.
Maybe anyone have experience with this?

Thank you!
