This were the same thing the so called meme coins were upto example is the doge, Shiba and now the Pepe. This coins are just simply pump and dump coins. If you get lucky then you will make large profits from them but as the saying goes same energy will apply to them dumping. In fact many scammers have found ways to penetrate into crypto space through lunching of this pump and dump coins and no matter any warning giving out many will still fall victim of these schemes, it won’t change because human are greedy in nature and many have the narrative that cryptocurrency is a get rich quick scheme and that’s why they prioritize this meme coins than bitcoin or even all this other top Alticoins.
My advice is those who invest into this shitcoins do not expect any return from them. Once you buy them just set that amount aside that it is not coming back, many say it is like a gamble I will say even sports betting as an iota of one winning than them. So just set aside money that you could lose easily and do not think of going into long term investment with them, once you see that it has gotten at a certain price and starts dumping do not invest in them thinking they will pump again. The best time to buy them is mainly before official launching or listing by top exchanges
