Smiles, if so we can as well classified them as memecoin since they are mostly hype just as memecoin, and we know that memecoin often come with hype which easily results to pump and dump.
Almost all the altcoins are also like the memecoin. Even before the arrivals of the memecoin (except those like doge and shiba inu), most altcoins at the time were pumped and dumped. I remember coins like digibyte, filecoin, qtum and many others that I thought would become better in the future but they got to all-time high many years ago and they can not get tonthe all-time high now as try are more than 10 times farther below the all-time high. Just that me coins is still the thread, almost all altcoins are like them.
