Building ~sustainable~ models to monetize and market unregulated capital gain just isn’t it. Cryptocurrency is never going to be ecologically just.
Part of the reason this is true is that cryptocurriencies are pyramid schemes. In a cryptocurrency marketplace, you make money on the people who have entered the market after you. This is not me on my socialist shit (which, don’t worry, I’ll get to later) but is rather just the fact of how they are constructed. Unlike a Ponzi scheme, there is no guarantee that it will all collapse someday- but the value continuing to rise absolutely depends on ever more users joining the network, using coins, and competing to mine them.
