Crypto trading can be an addiction to some people, just like gambling is. Investing in crypto, stocks, and gambling whether it's online or in a casino all have the potential to be a problem with people who don't have enough self control to do it responsibly.
well, crypto trading is better than gambling because on gambling at any point of time you'll lose 100% of your capital but unlike crypto trading, you'll only lose a portion of it because Crypto is all about increasing and declining in price values therefore you only lose the decrease portion of value and not the total capital you had invested.
it could be addicting too if you always gain profits so if you think you are skilled enough to trade then go ahead, there are so much lessons should be learned along the way.
