Caveat Emptor -- http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=6978842650&dcosts=4995&diff_mincrease=15&blpbtc=25&dhsmhs=5400000&diff_mincreasedecrease=0.5&btcusd=453.80&dpowcon=2500&btcusd_mincrease=1&pcost=0.115&calcweeks=32&dleadtime=9&action=calc#

This is with modest 15% diff increase (it will be 20% or more).

Please don't troll this thread. Thinking that the difficulty will raise nonstop with 15% is simply unreal and it's bad intended. There are other threads where you can speculate about the difficulty, but this is not the place and i won't allow it.I will just add that considering that the SP30 will be the most efficient miner starting from August it means that you will be able to mine for a longer period of time than the whole 50000TH/s that is plugged in right now supporting the Bitcoin Network. I don't want to continue this discussion and i will delete all further posts about it. Take it to another thread!

I think it might be helpful if you lay out how you think we should think of difficulty because honestly when I plugged the numbers into the calculator that I use I came to a similar conclusion as JWU42. Pre-order concerns aside that's really the the other thing that would keep me from going with this.

Edit: or even just link to a thread where you think has a good explanation of where the difficulty is headed.

I will refrain from making any assumption regarding the difficulty because nobody knows what hashing power will be deployed in the future and i don't want to influence people by telling them that difficulty will be X or Y. Everyone should make take their own decision based on what they find fitted for themselves, but i will only say that a nonstop grow of 15%-20% is unsustainable. If you think that it's not worth buying miners then there are many more like you which means that difficulty will grow at a slower rate than 15%-20%. For me it's simple. I will just give you an example. At 100 billion difficulty and 500$ per BTC having 100TH which consumes 100kW would make you around 3k$ per month that's not taking into consideration the cooling that you will need. Also deploying 100 TH means investing A LOT of money. Who would invest A LOT of money just to make a couple thousand per month? Actually if we take into consideration the cooling i think that you are already in the negative values which means the big growth will stop or slow down very much.

Again, take the difficulty discussions somewhere else please. Don't come here if you post something about difficulty and you get deleted.

I like those numbers, but I will fence sit. Make my mind up on the 25th.

I wish the wait was not until August. For hashing.

Your gear appears to be the nicest most professional gear I have seen. I can run 1 unit in house.

If you want to start hashing faster then reserve the spot by sending 0.1 BTC for every unit that you would like to purchase. Spoondolies Tech said that they will respect the reservation queue. Until now they have delivered the units faster than they said and i have a feeling that it will be the case for the August units too. If people speculate about the difficulty behaving the same as it did in the past i see no reason to not believe that Spoondolies Tech won't behave the same regarding shipping
