I used to trade with Poloniex but I do not earn a lot, my loses from trading is higher than my profit, I think due to Bitcoin crazy price up and down. Until I try Forex trading using WhaleClub, where I trade currencies using Bitcoin.
To be honest I found trading with real currencies like: GBP/USD, EUR/USD is more profitable than trading with BTC/ETH, etc..
Do you agree?
When you are more comfortable with fiat market then focus on Forex. There is nothing like better or worse way of trading.
The main determinant is your trading success and profits you can gain. Trading cryptotocurreny is not for everyone.
Crazy volatile market and sudden shifts of price might be frustrating, Forex is more predictable and easy to understand.
