He goes on to say "crypto is the poster child for the environment from 1990 - 2022 when we had unlimited volumes of capital. Now with that the money is going away, crypto is going away"
But money is not going away, they are actually printing more of it and right now the "capital" is too scared to jump into bitcoin. Not to mention that certain events like FTX collapse have caused a small crash preventing the rise.
When the inflation+recession growth stops, things could go back to normal and bitcoin would go up again.
Keep in mind that governments have been printing money like maniacs that has and will crash fiat's value which would only contribute to bitcoin price rise.
On future carbon taxes, which I agree with, the bitcoin network can easily operate on a fully renewable grid
Since such things like "Carbon Tax" are not global, they won't affect bitcoin. They are also not applied in any place with high bitcoin hashrate to matter and even if they did, the hashrate would simply migrate to a region with vast amounts of ultra cheap energy
