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.
Except for the king of cryptocurrency Bitcoin, and top altcoins like Ethereum, most crypto coins/tokens in the crypto market are risky assets, any investors buying them needs to do so with caution, so they don't lose their hard earned money. If you carry out a survey of people that bought different categories of crypto coins that are not among the reputable top choices that have remained in the market for a considerably long time, most investors don't have good tales about them, like you. Infact over 70% of them don't last, it's either some are scam projects from the start, some developer teams are not innovative enough to push them through and they die before investors are able to profit from them, then the ones that'll actually give value for money. So gamble your capital and hopefully you'll buy the ones that'll give you good profits, or not so lucky and buy shitcoins.
