This is a fairly small amount, I think the risk is not so great. But still times are very unstable, especially for violas. I would recommend investing to top 10 coins. Select multiple and divide this amount between them.
Everyone has their own amount, which is terrible to lose.If you want stability,you said correctly that it is better to take stable coins out of the top 10. But if you want to earn a lot more you need to buy altcoins with less capitalization
