Always remember that investment is a risk especially crypto. I think to invest in coins/ tokens in top 100 is also risk as invest in coins/tokens which are not in top 100, the difference I think it is profit, you can make more money with coins/token in the top 100. The most important thing you should to do is that you have to study and follow carefully the project which you invest in. You still can make more profit with coins/ tokens which are not in the top 100.
