Crypto is a failure because of design failures not because “it’s some control ponzi scheme”.

I take issue with OP attributing the problem through appeal to emotion rather than actually learning what went wrong. As you implied the tech behind crypto is very interesting and there’s a lot of value there that has been buried.

Now, idiots like OP convolute all of this process with idiotic reductionism that helps no one and will just lead us to repeat the same mistakes.
