Your video isn't loading, but judging by the title I can get the gist if what it's likely saying. It's disappointing seeing this outdated black and white negative misinformation being spread to here too, especially on the only current community on lemmy for discussing decentralization.
Purely talking about the title, ecocidal I'm sure is talking about energy usage. That is outdated misinformation by almost a year. Most development and use-cases for blockchain tech is happening on Ethereum or layers of Ethereum, which moved to Proof-of-Stake almost a year ago. "Ecocidal" might be accurate against Bitcoin (I think it's still a bit of a dramatic word for it, given what else the world spends vast amounts of energy on, including banking and finance infrastructure), but acting like Bitcoin = crypto is about 7+ years out of date thinking.
"Hypercapitalist" is just pure ignorance, I'm not going to bother arguing against this. There is so much more to blockchain technology and everything going on in the industry now than whatever you're imagining based on that word.
"ponzi scams" is the type of circlejerking garbage I was hoping wouldn't be dragged here from reddit. It's the copy/paste response every redditor has outside of crypto subs, yet none of them can ever explain what they're actually talking about and can never respond to any fact based counter arguments. The idea that all the development going on in "crypto" nowadays is just "ponzis" and "scams" is willfull ignorance at best, blatant purposeful misinformation spreading at worst.
I suggest you actually learn more about what is going on within the industry nowadays instead of basing your beliefs on ten year old information and then spreading misinformation based off of that. I'd love for Lemmy to have a higher standard for facts and information and a stronger defense against circlejerking and echochambers.
