I don't think that the government can ever save the cryptocurrency space. Once the government gets involved, there's a high chance that they won't just try to stop the scams but also regulate and have a power in cryptocurrency. Only us, the investors can save the crypto space by sending out good information to avoid scams. We must all be aware if a certain coin is good or not.
Unfortunately, nothing will help to avoid risks, even government control, and fraudsters will be always and everywhere. But for now, the reliable way is not to store everything in one place, but unfortunately they have other methods.
It is the crypto user himself that can prevent him from fraudsters in this space. Even if there are regulations from the government, scammers have their scheme to rekt somebody else's money. Because they can't control what sites user will visit or what project they will send their money to. So in effect, the responsibility is really with the user, how he will manage his funds.
