All trading is gambling in its core. You can lose your investment or you can make more money. Is is the very basic of gambling.
I don't agree with you because in trading if we have the skill to analyze the coins, we can make a profit. I think even if you are lost in trading, you still could make a profit if you have the patience to wait for the price increase back and not all people have this. and if they cannot wait the price is back, then they might be selling the coins at a low price and they lose their money. it is different from gambling which we cannot recover our money once we are a loss because the chance to make a profit is too low if we compare the trading itself.
