Bitcoin/Cryptocurrency

[Patrick]

What I mean is that there are implementations of crypto currencies that have all the qualities including being decentralized without requiring so much useless computational power such as for example Bitcoin requires.

I'm just saying that we should use a version that is not wasteful on resources.

There actually isn't, as of yet; it can be done, sure, but it's not close yet.  Bitcoin is now being mined using mostly renewable energy anyways.

Also, beware of the climate change "Green" movement, it's a scam.  It is heavily funded by Rothschilds, specifically.

How about an implementation such as this one ?
