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 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.
there are a couple of platforms that are offering margin trading both for bitcoin and other cryptocurrency tradings. the Chinese exchanges that everyone is talking about these days use to have it also but they had to remove it.
and i have to say i voted for cryptocurrencies because i believe the rules of this market is more understandable for me than the rules of Forex which is a huge market in a dog eat dog world.
