What we need is regulation, not for the price, but for exchanges, projects, ICOs and such. We lack guidelines for these projects and that leads to scams, thefts, etc. That is the only thing I can think of that we lack. If we're able to do this, then trust from the general public would be gained, next are the investors, and all will follow. If we can't avoid scams, we must somehow do something to prevent or penalize them.
Cryptocurrency don't need regulations or anything selfishly suggested by us, it is the majority that lacks something, and that is discipline, if only we all have proper discipline, no one would take the advantage of being anonymous in cryptocurrency to scam people by what you have mentioned, everything is going to be alright with honesty, and proper disciplinary actions to ourselves (though it is impossible) people nowadays are selfihs and only care for themselves.
