investing on crypto can be a good idea but can be a bad idea too
if you invest in crypto without enough knowledge, i think this kind of investments will be a bad idea for you
so, learn about crypto first before investing

The most important part of the knowledge to really go for first is how to identify bad project from good ones, for me, I think if you are able to differentiate the two, then you will be able to successfully make a very good choice and then have a benefiting investment. One of the thing that kills peoples money and discourage them is bad projects and scam projects.
It has sent a lot of people out of the crypto market, I use to imagine how much the total capital of cryptocurrency would have been right now if we didnt have scammers in it, look at the amount of money that has been stolen out of the market, and also consider the amount of money that would have been put in by investors, maybe by now, most of those top altcoins would have even gone 5x today.
