understand that meme coins will only move if there is hype. if the hype is over, don't expect to get more out of it. it would be better to choose an altcoin that has a clear developer, clear direction of creation. try more to read the whitepapper of each altcoin you want to invest in.
so I don't think it's right to make meme coins as a long-term investment.
It's not inappropriate, it's not even worth making meme coins as a long-term investment. Meme coins move only because of hype and usually don't last long, meme coins are only used to gain momentary profits for some people who understand and follow from the start, but not for beginners who come because of the hype and then invest, of course this is very risky.
Even Dogecoin is like that, even though Doge is said to have good fundamentals, many people suffer losses because of Doge Coin and not many people gain profits from Doge Coin. More precisely, we have to be smart in looking for moments.
However, if you are lazy to reset, it would be wise if you just invest in the top altcoins or it is safer to invest in bitcoin for the long term.
