Thats not a reason for crypto being useless, anything can bribe corrupt governments to pour tax money into it.

Crypto has shown people are willing to use it as a currency for investment and day to day transactions. Its held value for a significant amount of time. The tech is evolving still and people see a lot of value in having a currency that operates outside of Governments in a decentralized way even if some people will misuse that freedom.

> day to day transactions

Where is this happening?

Money laundering? Certainly.

Black market goods? Of course.

Avoiding taxation? Absolutely.

Day to day purchases? Not that I've seen.
