If big institutional 'groups' are formed and they buy crypto suddenly, then manipulation will take place. If institutions hit exchanges one by one, the growth will be stable and the manipulation curve will decrease upto some extent. It can be noticed that btc or any major cryptocurrencies that are here to stay, will not see sudden falls and if they do, they will be bought up by new institutions and will remain stable and can only grow till any institution decides to leave crypto after taking out their profits. We saw Elon adding #bitcoin to his Twitter bio and btc saw a quick pump, imagine what will happen if he tweets #boycottbitcoin
