To be fair, almost every niche in crypto is susceptible to manipulation, and I agree that it's more frequent with memecoins, but we still cannot ignore the fact that a lot of people also profit from the space, and by this I mean average traders.
Cryptocurrency has a huge influencers and its market is driven by community activities so for sure, there is no cryptocurrency without manipulation, it is the manipulation that gives birth to the volatilities in the market and also the chances for investors and trader's to interconnect, as actors in the market, so you are right in that statement, but what I want you to know is that market manipulation is weighed on different levels and at that we can't compare the level of manipulation in meme coins to be the same as that of Bitcoin or Ethereum it is not possible, while Bitcoin is open to market forces to manipulate it which is hard, meme coins are being manipulated and controlled by the developers or the whale behind them, so is easy to get pumped and dumped at will.
