It is necessary to study very well those projects in which you invest your funds. Then it will be much easier to wait for price growth. I still keep some tokens that have not made a profit. But I believe in these projects, I am ready to wait a very long time.
I think the study of projects will not help, it all depends on the person how patient he is. It is better to buy coins and forget about them for a year, then if the project is good then the person will earn a lot of money.
