while this is certainly true, it is also true that almost all mining equipment deployed since the advent of the ASIC era will never ROI in BTC terms


say, for example, that you had the foresight to preorder a BFL single in July or August of 2012, they cost $1300 at the time...BTC were $13, when you finally got your unit, a year or more later, sure, you could mine back your $1300, but no way in hell it will ever mine 100BTC

I have been mining, on a small scale, since the GPU days, and I would like to stay in the game.  At the moment the HashFast Sierra batch 4 1.2TH looks like the best bet, but it is $6300, and if I'm going to invest $6300 in bitcoin right now...I'm going to buy fucking bitcoin with it, not a spot on a waiting list where I can watch the delay announcements on the forum as the difficulty skyrockets.

just my opinion
