Bitcoin mining "profitability" is a shitcoin.

Here's why.

The profitability is calculated off of current price. AND it's always expressed in fist dollars. Any Bitcoiner worth their hash knows to lower time preferences and to measure Bitcoin in Bitclin.

So in this sense... the sats you're earning are going to be worth substantially more in the future. So you're giving up fiat now to be recouped greater down the road. Now if you also use the miners for heat in your home... it's win win!
