exactly, some people made their side hustle by simply trading derivatives and thats already sufficient despite all the risk involved because we know the risk is also there, but some people that successfully traded their money whether for futures or spot and could make profit are definitely the ones that sees good effect of crypto in their current financial situation.
it could definitely help them to increase their income up their game, live a life they wanted from the very beginning.
it all depends on the will of an individual if they are willing to find opportunity they will definitely earn.
if they just want to get rich quick then i won't be surprised if they instead losing all their money.

remember to increase income it needs some process and skills, without that its almost obvious that things won't end well, same thing with crypto it requires knowledge and strong will, then someone could earn much more income.
