We will always hear this kind of stories especially during the bull run, some people will lose, while some people will make money. The sad reality is there's a lot of newbies who are convinced that trading or investing is profitable, but in reality, it depends on your knowledge and skills, and it's like gambling where one could make or lose.
Yup, newbie who are so aggressive lack of knowledge but only guts, they are the one who've become the milking cow of those playing around the market. The problem is, some of these newbies are victims of so called hype in social media and they are the easy target, we all know that in trading, someone will lose and someone will gain money from losers.
Futures and leverage trading are risky business and people should not venture towards it unless they have plans for every market movement. A good trader should have loss stopping strategy and know where to book profit. For lesser risks, it's better to trade with your own money as even though the price crash, you'd not be liable for more than your own money.
Investment on the other hand is a much laid back approach towards crypto. You don't have a loss until you sell for a lower price than you bought. Historically crypto always had been on upward trend and having patience in investment would pay sooner or later.
