Dangerous or moon is according to the trend of crypto market, but its not recommended to buy memecoin nowadays because the leader of Memecoin Doge in the top already. Others memecoin will follow the trend of DOGE. Without any use case and strong fundamental alot of copy DOGE will fail and in bear market can be dump more than 90%.
Depend on whoever promoting it and most likely people will no longer take it seriously after what happened to Dogecoin this past few months. Nowadays, if you want to invest in some meme tokens, you need to consider the danger and the risk you gonna get when things do not go well in the market because if the market became bearish, no one really put their money on some mere meme token when the opportunity is in the bitcoins itself or in the ETH. Most of the people won't care about the meme tokens whenever the market is not flourishing, they're going back to the top altcoins to regain back they've lost.
