Especially with high leverage trading, the price is too volatile to make very much money unless you have insider info or so a lot of money to move the price.
Yes and especially because so much luck is involved in trading. That's why I prefer to not trade I don't like activities which I can't plan out and trading is one of them it's either up or down win or lose, skill helps more luck is more important hence why its unpredictable.
If luck was the more important factor in trading we will not see common people earning a living in the stock, forex, or altcoins markets, its just that trading is a lot more difficult than some people think, that is all.
