Cryptotrading is just like normal fiat trading, just more volatile with increased risks.
If you're good at it, then it's a great profession. If you're not good at this then you're just going to waste your money.
Trading in a market like forex was already very difficult and the volatility of the cryptocurrency market makes it even more difficult, while many people that enter this market thinking about becoming rich thanks to trading the truth is that I think that in this market there is an even greater amount of traders that are losers because when you mix volatility with and inexperience you can only get losses.
