Also most low marketcap coins are very easy to manipulate and they are the ones that the manipulators mostly visit. Those slightly high and high marketcap coins are still not completely resistant to manipulations but low marketcap coins are the riskiest.
These are even happening with famous cex like Binance. Sometimes youll be able to see some tokens that arent much moving before suddenly pumped to 80% to more than 100% thats because probably of cabal whales trying to move it. Ive witness howbsome of these guys pumped a coin and Id say manipulations exists even with top market exchanges. Also with good project that has narrative not only memecoins.
