Moral: I think BTC and ETHEREUM is better option for investment, Can be trusted blindly, profitable for long. Low Ranked Altcoins, Memecoins and shitcoins are just headache and reason of huge losses in long time. But anyone can invest his money wherever they want.
As if he voiced my thoughts, there are also a lot of coins in wallets that cost nothing, and how much time I spent on this is just terrible. I should have sold what I earned right away, but I decided to wait, in the end I didn't get anything. Don't make the same mistakes.
However, in essence it is true as you said, the right choice to invest is only in bitcoin and etherum because it is proven that it continues to grow and the community is getting stronger and the fundamentals are also good for the future. Investing in altcoins is like gambling, the risks are too big if you can't analyze them well.
