I have to say, I think it's dumb. I try not to be a crypto-bro. And some points are accurate (how can something be a stable currency AND increase in price?!). But others are foolish:
* having no ability to reverse a transfer is exactly the point of cash, and reversing transfers is a classic source of fraud in and of itself.
* the claim that crypto has no use case. First it's an opinion, don't lay it next to facts and try and sneak it through. Second, that is fine, don't use it. But don't tell people who do they can't have it because you don't need it.
The thing that amazes me the most about crypto is how it continues to be either the messiah or the anti-christ. It's neither. It's a bit of a novelty, it's useful for some specific cases (hyper inflation, evading state controls be that good or bad). There is a lot of dishonesty, but that isn't the tech's fault. That human nature, refusal to regular and gullible idiots thinking they can get rich quick. It's no different to the early days of any other security.
Errors made should always be reversed by a separate transaction for an audit trail.

Sorry could not find a link..
True however the true cleverness was that they burn the fumes coming off the sewerage system safely disposing of formally dangerous build ups of the gas while getting brighter at the same time.
So essentially fossil fuel is only a part of what they burn.
