Puppet,
I am starting to think that all BTC mining operations are like a dog chasing its tail in terms of turning a profit. Let's assume that difficulty will go up as you say and that PETA will not make a profit. Do you think that all Bitcoin mining operations will also end up in the same situation?
What is your take on DTMA & DTMB? (a couple of other mining funds soon to be offered on Havelock)
Do you foresee them being a success given their 6 month window till deployment?
Keep in mind that the profit from mining is taken by the manufacturers. Do you really think that someone would sell you something for less that it's worth? After the miners become no longer profitable (no longer able to achive positive ROI) they release it on the market for huge profits, didn't we saw this time again and again? Mining is no longer decentralized.
