I want to mention that Alt-coin is now high risky for investment whether it's for long-term or short-term. The market is in such a bad state right now that anything can happen, so I would advise you to refrain from investing in any kind of alt-coin right now. And currently, the new coins can't survive in this situation or they are scams, so if you have to hold or invest, I suggest you to suck bitcoin. However, it is better to use lazy funds to invest.
Another thing we need to realize is that true decentralized ones will not be controlled and that means only we are in charge. Sure there are plenty of project with devs at the top who can do whatever they want, even as high as BNB where we could see CZ do whatever he wants, but the real decentralized ones where even the dev can't do anything, means that it's only us in charge, so we could make it go up, and nothing in the world could ruin our fun there and only we would sell it o make it go down.
Obviously that sometimes happens, look at the bitcoin price for the past 1 year and how it dropped, we know that it's decentralized and still went down, but that's a good buying chance.
