The one and only intention behind every investment is returns or benefits so there is no doubt in that people who are investing in crypto is to become rich but what they are trying to do is to achieve something in no time which may happen once in a while but not for everybody still they hope they can be that one and investing on shit projects which claims to be giving high returns.
Most people are investing in that way but surely there are exception for example if they are already having financial and investment related experience then surely they will do enough research about what investment they are going to make and what are the risks behind it and how to minimize it, etc.
It's a matter of taking risk or not for a chance having a good and mostly they didn't give some time to prepare even though they may have experience in investment for example and didn't do somr research before investing in that project or platform then getting scammed in the end. As explained in previous post in this thread that the less knowledge you have the more you are to fall in a scam situation which we don't want to happen. I think that the reason behind that bis because of other people's success in crypto which make most newbies being impatient.
