You mean just like after the 1929 stock market crash we just improved stock trading? Or after dotcom crash we became more serious about evaluating usefulness of services? Or after various mortgage issues we introduced controls for known issues?

I feel like it's similar to any other huge system. There are issues with it. We prevent some behaviours and provide incentives for others. We don't lose faith in stock market and burn it to the ground.

By definition, they are not ponzi schemes. None of your claims are obvious, and implying otherwise is disingenuous.

>But we better find out what the future is before they start converting the gullible masses to a currency that is less secure in many ways that is swept under the rug.

Ah yes the "gullible masses", and the wise men and women who know better.

How about we respect other people as adults who have a right to buy whatever they want with their own money and stop trying to treat them like sheep that need to be protected from their own gullibility. Your presumptions of knowing what's best for them, to the point where you'd like them to be denied the option of buying them, are extremely condescending.
