I believe crypto, mainly the blockchain tech behind it, is the key to restoring power to the average citizen of the world. For so long governments and big banks have had the most control over how ordinary people spend their money. Blockchain is wresting the control out of their hands and back into the hands of the people. On top of that there are other aspects of society blockchain can improve, such as voting for instance. You cannot hack or cheat or fool the system in any way, there are entire countries that would change overnight if citizens knew their votes would matter. Blockchain will be viewed 50 years from now as the thing that started the world to get better overall. We've still got some hurdles to overcome I feel but overall I think it's better for the world long term.
