It seems to me that it is beyond our control. Indeed, countries can take measures, or rather if governments start to recognize cryptocurrencies, rather than alienate from them, then fraud will be punishable. And now anyone can create projects and pass them off as an innovative, revolutionary idea.
It's not that much beyond our control, actually there are so many ways to spot a scam but the only thing we need to do is figure out where are them .
Those things will not be easy to spot that's why we need to spend much time on it.
