Most of the money that exists, does so in digital form. Money, whether state approved or otherwise, is disastrous for the environment. If it's not the creation of it, it certainly will be the use of money in its' entirety that is hazardous for anything alive.

I would have to agree. Crypto currency is essentially an evolution on money, and it will continue to evolve and improve as it matures in the market. Lots of hit pieces lately.
