Actually meme coin is high risky. It chould be profitable huge and chould be loss huge. I think it is like betting. If luck support will be huge profited. But if luck no supported then huge loss will happy. There are many popular meme xoin available in cryptocurrency market. Like, Doge coin, baby doge coin, shiba innu coin. I luke Doge coin and i am Holding Doge coin still now. Doge coin future is bright i thy. Because some days ago we saw world famous person Elon Musk promote Doge coin. And after that Doge coin price huge increased. I think it will continue. So i will Hold it for long time.
When you say meme coins are risky, you are right, but they are not just risky, they are extremely risky, and holding tokens or coins that are extremely risky is a very risky move. Nothing is permanent when it comes to meme coins or even normal altcoins, because one day they are up, second day they are down by 50% and that happens so quickly that you don't get time to sell your holdings. That's why, it's not recommended to hold such cryptocurrencies for long term.
When it comes to dogecoin and its relationship with Elon Musk, it's complicated. He does tease doge holders every now and then either with Tweets or signals but however, it is not guaranteed that he will keep doing that in the future as well because he has never shown open support for it or any other cryptocurrency in the market.
