> Whatever your stance on cryptocurrencies are, what is of little dispute is the business opportunities they have created

I strongly dispute that claim.

After a decade of effort, tens of billions of dollars invested, and thousands of crypto startups, we still don't have a single successful business other than those selling crypto services. (To be fair, Brave looks like it might make a run for it. We'll have to wait and see.)

Pointing to the fact that some people arre making a lot of money does not validate a business model or a social good.

Even in the most vile and egregious scams, there are always some people making a lot of money.
