It can happen in some situations. I have people who tried to give me money to invest, as they saw me making money. I declined as it would probably make me a bad investor, as i would change my methods when i would be responsible of someone elses money. Also i wouldn't want to provide info about every trade and tx fee for tax reports. It seems like a lot's of work. Combined with the burden of responsibility.

These people approached me because they didn't know anything about crypto or trading. They wanted someone else to do the work. Same happens when you don't know anything about sports or sports betting. But you see someone getting rich by it. They want in for the profits. This makes more sense to me as i understand trading and crypto but i don't understand sports betting as a deep level as crypto scene. If i saw someone making bucks with gambling, i would definitely want to fund it. Especially in Finland as gambling winnins when playing on "veikkaus" are tax free income.
