I would suggest to buy such memecoins only when you are 100% sure that the price won't be dropped down from the level you choose. If you are pretty sure in this and you understand that future pumps are inevitable - then why not buy this crap 
There's nothing like that nor a guarantee by buying the meme tokens. You must need to sure that if meme token will always give you 50% :50% to increase and to decrease. This can't be denied. as long as people have been taking it as a part of their decision and they are good when they must deal with the risk of investing in the meme token. that's why people are hating the meme token coz it's pretty similar to the pump and dump scheme. People are hating meme tokens caused by rugpull and yesterday baby musk was doing rug pull to the its liquidity pool and the developers has been running away with 14 millions USD.
