1. Don't invest in crypto if you can't afford the loss.
2. Don't put your eggs in one basket.
Diversification solves many problems. I see in this section that people often wonder how many altcoins to make up a portfolio. Some people think that they can make a portfolio out of 2-3 assets and that will be enough. My answer is NO. This is too risky a portfolio, more like a speculator's portfolio than an investor's. In order to minimize your crypto portfolio losses due to events like what happened with LUNA, your portfolio should contain at least 10 positions. I understand that for those who have little money, this option will not seem profitable at all, because let's say invest $500 in 10 projects and the amounts will be ridiculous. But this is exactly the mistake of such beginners, which describes OP, they will choose $ 500 in 1 project, because the profit of $ 500 seems more than the profit of $ 50.
