If someone loses, someone else gains. As long as you are smart enough and patient enough, you can actually make money. However, in my years of trading cryptocurrencies, my experience is: not many have the courage to change themselves. Most people find it troublesome, feel incapable, believe they will definitely lose money, and think they are being rational. Then they continuously miss opportunities, and when they see others making money, they can't help but go all in, only to lose at the peak.
