How is it that possible that someone can lost in Trading when he or she is making huge profit?
Crypto trading is just like gambling/real-life trading which economic inflation can impact the future price of the product you're saying. If a trader is making a profit and not extra careful, takes a profit, and also manages risk he can lose all the profit he once made in trading.
This is the reason why consciousness is said not to be foolish and every day is not Christmas.
