It is not necessary anymore if you are only investing in potential altcoins like Ethereum. But if you are in these shitcoins and new projects, you'll gonna do that otherwise it makes you surprised that your portfolio had gone ZERO.

Investing in altcoins isn't a bad idea but investing in new projects is a different story and riskier. As an investor, we need to learn how to assess the projects before investing if we need to avoid losses. Scam projects are flooded in the market which is why we should be careful and cautious with them, especially for hyped projects.
