When difficulty rises and your GPUs start operating at a loss for a good cause (which is secure and free money) you will no longer support this good cause,
but instead support another good cause which makes an even bigger loss (due to the same high $ per kWhr costs, but without anything in return at all)?
So, instead of paying let's say $20 a month to get $10 worth of bitcoins back, you decide to pay $20 a month and get nothing back?
Is it just me, or does that seem weird?
