You can invest anywhere you want, no one has the right to stop you because it's your money. I have no problem with people investing in altcoins or memes because the choice is theirs. But I want to tell you that don't give investment advice to anyone when you have no knowledge about it or haven't achieved anything significant with it. Don't look at articles about people getting rich quickly by investing in memes and shitcoin,  and quickly assume it's easy to achieve. Also, don't give shitcoin investment advice to others when you don't know anything about it or you haven't had any success investing in memes.

Investing in memes is extremely risky, if you like you can try it but please don't give that advice to others just because of your naivety.
