If I'm not mistaken the hardware should become unprofitable not too long after June 30th.
With a difficulty increase of 30% (very conservative, borderline hopeful), a hashing rate of 180GH/s, and monthly cost of $49.99
all calculators seem to be pointing to the same date June as the month in which the ANTMiner S1 Hardware becomes unprofitable.
Generating more or less BTC 0.234242
The Neptune same difficulty 30%, 3000GH/s same monthly expense will be profitable until the end of October.
Generating more or less BTC 0.0490592
To total profit should be BTC 0.2833012
Am I wrong? If I am please please point out the problem.
I don't want to discourage or troll I'm just trying to do my due diligence before investing.
Actually (full disclosure) the operating costs are higher, closer to $200/mo per ANTMiner. The anticipated power and space requirements for a neptune would result in around $500+/mo per unit. Mining calculators that assume a static price of BTC, with sustained exponential growth of hashing are flawed. Also the hardware will continue to have value, and can be liquidated for further return. We have other options such as underclocking for efficiency, once we cross the space barrier in the datacenter. We'll be moving from a single cabinet to an 8 cabinet cage if we can continue to grow the operation.
Hoarding looks like a better option on paper, but hoarding doesn't grow the bitcoin economy, spending does. This is something you can spend on that will give you a future return of (hopefully more valuable) bitcoin.
My GPU rig that I put together in Feb 2012 unbelievably is still profitable... Of course your milage may vary, don't invest more than you can afford to lose.
