Just choose altcoins to invest in that have a working product, not by their popularity. Indeed, research is very important but it is not necessary anymore if we choose ETH and the top 10 leading altcoins in the market. I have ETH, BNB, and Matic --they are worth investing in and have been proven for their profitability for many years which gives me confidence.

Talking about risks, cryptocurrency investment is quite risky in general. Perhaps, that was natural in any form of investment but choosing the right projects seems to solve the problem. Choose old projects and stay away from new projects, we can be safe.
