I saw this on hnews today: https://blog.cryptographyengineering.com/2022/06/09/in-defense-of-cryptocurrency/
- Such raw naked hunger and greed on display here. 
- Literally burning enough energy to power an entire country to run hashing algorithms. And the days pass with hollow promises of better tech. 
- Fix that first, fix that now and show the world your community actually gives AF. 
- But you will not. 
- Nor will your community. Crypto is fine and happy to help make the world burn hotter. 
- If you hold bitcoin or mine bitcoin you have blood on your hands. 
- It is that simple. 
- Until bitcoin is stopped none of the rest of the article matters. 
- Regulate it? Attack it? You pick but either way it must be stopped. 
- The crypto community has no will to do it themselves. 
- The tech is interesting to me but a central database solves most of the problems and does not burn the world in the process. 
- Hopefully the newer blockchain tech will take over but I doubt it highly.

I also consider Bitcoin as a stupid waste of resources on a global scale. All proof-of-work tokens are a disaster IMHO since the security is based on a proof that enough processing power has been spent.
However, there are many other tokens based on proof-of-stake which do not waste energy and are more efficient. These make much more sense IMHO since they are more ecologic/sustainable.
