You are wrong!

Okay, the banks might cause more carbon emission than blockchains. But, the banking system serves the whole world, providing services for 8 billion people. But Blockchain is still a niche thing.

You might say, no, Bitcoin is not niche, Blockchain is used by a lot of people! Then, you are wrong again. The media is talking about Blockchain all the time, but it is indeed a niche thing. No one is using, say Bitcoin, to buy real physical stuff, cryptocurrency is not taking part in the people's real life.

So, my point is, if Blockchain is adopted by the world and replace the banking systems, it will definitely emit much much much more carbon, I am saying orders of magnitudes more.
