Unfortunately, given:
"How can we create a more equitable financial system, where everyone has access to banking services?
How can we reduce the power that a small few currently hold over the web?
How can we improve data privacy and ensure that people have control over their personal information?
How can we create reasonable privacy in the financial system?
How can we make information more available to everyone?
How can we fix a society where so many people are in untenable financial situations?
How can we reduce the enormous wealth disparity in today’s society—both in the existing distribution of wealth but also in access to new opportunities to earn it?
How can we enable creatives to make a fair living from their art?
How can we address inequities on a global scale?
How can we create self-governing communities around shared interests or goals?"
Cryptocurrencies as a tech are not the answer for any of those questions, they could be a tool to support some of those things but as of now are not the most efficient way to improve those. Maybe the "movement" / hype behind cryptos could help but you have to an absolute uncynical person to think that given the types that are most loudely hyping it up, society won't be worse off in the end.
