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?
if you trading in poloniex is same altcoin trading
altcoin trading is high risk but high return and not margin call, you can't lost all money
forex is high risk high return to, can lost all money if margin call, but price can control, price can prediction about resistance and support price
in altcoin price can't control can incraese high price, and can crash and down until very low price
