Seems like a terrible thing to invest in.
It gets more difficult as it goes along, requiring more power, more hardware, more energy...
At some point doesn't it break some kind of negative even, no matter how good you're doing? Eventually, it would have to be worth an extravagant amount to make it worth mining.
Isn't it a straight shot right into the garbage at base value?
The "difficulty" of the problem being solved automatically adjusts.
