The TOS of Bitmine.ch do not actually allow for the contracts to be transferred so you would be risking that any buyer would have the contract revoked and/or given back to the seller

Why don't you just keep the contract and hope to get back even a small portion because there is no way anyone here is going to give you 62,000 for it. You can get the same amount of hashing power from bitmain (with S4s which are overpriced as well) for $26,250 roughly. It would require 21 S4s though, but someone who had that amount of cash on hand likely has a place to host them.

I won't even bother to bid because as a previous poster said all realistic (and smart) offers would have to be below 10 BTC.

More seriously, here is the mining revenue over 6 months, it takes as a reference 10% difficulty increase at each round  :


Sure that is the revenue with no maintenance, why don't you use the calculator to put that in as well to provide the expected return since that has a MASSIVE impact on the return, in short it will kill most of the BTC as your original screenshot already showed...

So I took the opportunity to factor in maintenance as you stated, since it is USD against BTC at the time it is due best we can do is use current value... At the 10% you estimate in about 88 days the contract will go negative, what is Bitmine's T&Cs on that, in short are you obligated to pay when the mined coins do not cover maintenance?

I doubt that contract will ever go negative, you are simply spreading FUD.

Really? I used YOUR difficulty estimate increase you used earlier and YOUR maintenance price.. It's basic math and I asked a serious question since i want to understand the details before bidding but if you want to be an asshole then perhaps you should fuck off....

You'd be wrong in assuming new products wont drop Q1 2015

i am sorry, i messed up the message. This is what i wanted to say :

As the difficulty increases  without a price rise, more miners will be soon forced to shut down. I am not sure we will continue to see the kind of exponential increase forever, of course mine is just a conjecture, as it is yours, nobody knows the outcome for certain. Besides, i am selling the contract just because an unexpected problem and immediate need of liquidity. What is your offer ?

Cheers


You are correct that we will not see exponential increases forever but I can say that it will likely increase by a good 9% in roughly a week or so and difficulty has increased by at least 10% with very few exceptions this year.

I am not sure you would want to see my offer as it would be well under 10 BTC (while you are asking for 45) nor that you would even take it seriously.

Your observation is correct, although during the last year we witnessed  big changes in the mining scenario. For the time being there aren't new products being released so i am not expecting a massive rise in difficulty.
I'd be willing to accept a reasonable offer, but i am afraid that anything under 10 btc isn't going to make it.

I will sell this contract for 45 BTC, you can clearly make a good ROI with it Smiley


Also do you have a reserve price? You mention what Bitmine.ch is charging on their website but fail to mention what you are willing to take for it
Maintenance fee is 80 USD / TH / month
Oops, it looks like I missed that. If maintenance/electric cost is $80 per TH per month then it would cost $3,360 per month for the entire contract for maintenance.

Assuming that difficulty increases 10% every 2016 blocks then maintenance would exceed revenue after 75 days and you would have lost ~37 BTC on the contract. If difficulty increases by 5% then maintenance would exceed revenue after 145 days (which is just before the end of the contract because it is already a month in) and you would end up losing ~30 BTC. If difficulty goes up by 1% then revenue would exceed maintenance for the rest of the contract, however after 162 days you would have lost ~14 BTC. In order to have any kind of ROI on this contract you would need to have difficulty decrease by ~2% every 2016 blocks (something I would consider extremely unlikely, especially over a 5 month period) which would result in a profit of ~1.9 BTC on a 45 BTC investment or a ~4.22% return.

Your projections are too pessimistic. It remains to be seen what will be the difficulty adjustment for the interested period of time.
What part of my projection are too pessimistic? My calculations assume that the miner would have 100% luck (which is really all you can assume in regards to luck).

From the looks of it bitmine.ch is selling horribly overpriced contracts. If you can find an error in my numbers/assumptions/calculations then please let me know, as I may be interested in the potential for ROI is right.

No, you're not looking at 10% each "round," you're looking at 10% each month.

This makes an enormous difference as this would mean ~5% each difficulty adjustment.

Yes correct, i did not notice it is 10% monthly difficulty increase.

IMO 10% per two week period is most likely too low of an estimate when calculating your potential ROI. The median difficulty increase has been closer to 20% ever 2016 blocks then 10%. So your chart is under estimating the likely difficulty increases by a factor of at least 4

You should make this more clear.   I've never once heard a month referred to as a "round" when talking about BTC difficulty.
