Fixing something that already broken is harder than making a new thing, but that doesn't mean to be impossible to do that, i think the first thing to do is restore the trust that every people had toward cryptocurrency.
Trust is important for building a positive attitude so you can be more enthusiastic and manage well.
Crypto is currently in poor condition but believes that it will improve even though it takes a process and it is not easy to restore it as before but there are still opportunities even if it's small.
