Memecoin is another part of Cryptocurrencies and it has been a live changer for a few and a big deal to those who lost plenty of their hard earned money into it. It is risky to invest in them but if the investor should experience a bull market in the system then for sure he has a lot profits to talk about.
Investing in meme coins is very risky. If you are lucky you will get a return of up to tens of times. But if you fail you will lose all your money. But I don't think meme coins are ruining crypto. Many people get to know crypto because of meme coins and then they get to know other coins which are actual crypto assets like Bitcoin,Ethereum or Bnb. And like NFTs, Meme coins will always have a role in the crypto ecosystem even if it is a risky gamble.
