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?
Using trading altcoin is very much profitable than trading in Forex. Though you can make a huge profit in Forex, but it is also risky one wrong move Forex can make down your funds. Unlike in bitcoin/altcoin trade you can minimize your loss anyhow.
