Is crypto a good investment?

Hello, I've been hearing a lot about cryptocurrencies lately, and I'm curious if they're a good investment. I understand that they're volatile and carry risks, but I'm also aware that some people have made significant profits from investing in them. Could you provide some insight into whether or not crypto is a worthwhile investment? Are there any specific coins or tokens that you would recommend? And, finally, what are the key factors that I should consider before making a decision?
