No we dont need regulators or regulation because like what you said this only kills the main advocacy of cryptos and that is to become independed or decentralized . however many have said that regulation can help the price to increase because it can attract people to think that crypto is already legal but they didnt know that cryptos are already legal in the first place .
dump or not , cryptos will still have a good future . we can tell if we look on our sorroundings , people are already aware with crypto and many business and merchants are already accepting it .
