Well, the MISTAKE miners are making is they are calculating break-even using current or near-term BTC prices.  5-10-20 years from now, assuming mass acceptance, a BTC might be worth several orders of magnitude more than it is today.  So, taking that perspective, BTC .00001 tomorrow might be worth the same as BTC 1 today.  It is a risk, for sure.  It is a stretch, for sure.  It means mining at "losses" today, for sure.   But years from now, continuing to mine at a loss today will be seen as having been a brilliant move when BTC .0001 pays for your grandchild's university education.

Just something to think about.

On another note, I do think eventually BTC mining will be essentially centralized as the cost of machines required for big BTC mining (I'm suggesting 1+ BTC per day will qualify as big mining) continues to increase in power and price.  Then, as per design, "old technology" miners will profit from transaction fees, instead.

Just my 2 satoshi...
