Price manipulation will be the biggest harm to cryptographic tokens, expecting a more regulated market
This will not going to stop unless there is some changes that is going to apply to the blockchain and Bitcoin itself. It will keep on happening every now and then unless there is someone make a move but i guess the people are getting into it but when prices is going to rise we will suffer from the sudden rises of every fees on the exchanges so i think there is some disadvantage and advantages for everything.
