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?
Two types of this platform has each advantages and deficiency. For example, in forex trading there is a rule that called margin call that can make your money completely used up, but you can't find it in bitcoin or cryptocurrencies trading platform. So your money is safe even if the price drop to 1000 point.
If we talk about profit, a man knows god never show us where is the money. If you think you get more lucky on forex trading, then develop your skill on it.
