But, I think that the break even will still not decrease from deposits completing. Deposits completing might just keep it at 31 months. Cause, as difficulty rises the breakeven takes longer and longer.
That's why I think they should do something like 50% fixed mining , 50% polled mining. Or maybe 30% fixed mining, 70% pooled mining. And if there is ever the case that the current hardware options is really good then the old members will get an advantage. And if its like how it is now then you're going to be getting more than an old investor but you'll still be benefitting the old investors.
The problem right now is that as the investment becomes less lucrative less people invest which means less growth. Without growth hashrate will just stall into negative (does pyramining take fees for electricity?)
What your not factoring in is threefold. 1) We have the hardware he installed that was approximately Double that of the asic queue.
2) The deposits that are coming in either fresh or reinvestments that allocate more of that extra hardware to the entire system. 3) The finished deposits/accounts whose hashrate gets divided up among the remaining active accounts.
We also cant forget that he set the amount of active deposits in stone so to speak. If the hardware doesn't exist deposits will stay queued until either more hardware comes online or older deposits get paid out and free up some hashrate.
In summary, as he has said, do not worry about the difficulty. As long as he keeps bringing in more hardware it will only get better from here. He has also brought an additional 200gh online in the past few days. Thanks to this and some very large deposits my equivalent hashrate has increased over 10% in that time.
