...calculated using an ideal AntMiner S7...
Q:Is the PACMiC really risk-free?
A: Like all forms of bitcoin mining, there is a certain level of risk involved. If network difficulty unforeseeably skyrockets, or if the price of bitcoin drops too much, the Antminer S7 units backing the PACMiC may not be profitable to run and be forced to go offline, in which case contracts would be suspended (possibly indefinitely) and the user may not recover the initial cost of the miner. However, the AntMiner S7 is currently the most power efficient bitcoin miner available on the market, and would be among the last to be forced to power down under unfavorable market circumstances. It is our comprehensive evaluation that the likelihood of PACMiC holders not recovering their initial cost is indeed quite low. We ask that all users please understand the risks inherent to any sort of bitcoin mining, and also to understand that there is no such thing as a risk-free product.
It looks like they have updated the PACMiC v4 to be backed by S7. I'm pretty sure on release it appeared to be backed by S5.
Does anyone know if the S5 wording was in error?
What happens to previous buyers of PACMiC v4? Do they have backing from S7 or S5?
It's not like Bitmain to fuck something up like this.
