I would have to agree that the main missed point here is the cooling situation.  500 TH/s is a lot to cool, and 5 PH/s needs pretty much a dedicated facility built from scratch to maintain that.

Also, you are quite a new member, and no offense, but in the past new members who come right out and say send me miner gear/money usually don't end up doing to well.

At least its a better deal.  You will make back your investment as opposed to not being able to recover your funds.  Interest sucks compared to V3, but its better than nothing.

Nope, you seem to be doing the math correctly. There is other value besides what the miner mines as well though, like residual value of the miner.

Looks like the description of V4 has been changed to using the S7 for hashing.  Not a great return, but at least you can now get your money back before the unit becomes unprofitable to run.

I will now be buying a few.

Ehh only very few are buying, probably the same people who are going to come back in 120 days, when the S5 is no longer profitable to run, and complain that they are being screwed by Hashnest and its all a big scam instead of admitting that they made a bad investment.

I think they are still on holiday until tomorrow, so perhaps when people start getting back into the office and noticing that it either wasn't offered correctly or something, they will take another look at make a better offer for V4.

Or maybe it was off topic and not pertinent to the discussion/untrue.  Can you share the hard facts that were brought forth in that thread that specifically pertain to them being a scam?  This starts up every couple of weeks about how it is impossible to have as bad as luck as they do, but no one ever presents hard facts, and they only seem to complain in the downtrends, but are perfectly happy to accept the times where luck is above 100%.

Also more initial capital.  I believe you must put in 10 bitcoins minimum.  But yes higher interest rate, but still the ability to withdraw at any time, you just lose the interest accumulated for the current month.

Update, my deposits have shown up.

How many confirmations normally does it take to get coins in?  I have 10 confirmations and they haven't shown up yet.  Will email support.

Your account is worth what someone is willing to pay for it.  Not a penny more nor a penny less.

I think investors are showing that they know its too risky and are not buying much of the V4 contracts.  Over a day running and less than 400 TH/s sold. The V3 had petahashes sold in the first 24 hours.  Hopefully Bitmain will get the message and structure this better.  Even basing it off of the S7 will allow me to buy some of them knowing I will be getting a return, although less, I will at least have a chance of getting my funds back before its unprofitable to run.

It doesn't look like they have posted a new thread yet, so my analysis will go here for now...

I always start by looking at how long the contract will take to pay off at a 5% diff increase.  At current price level and 5% increase, 1 TH/s will pay back 1 btc in about 170 days.  Much higher than where we used to be for V3 and V2.

Then, I look at how much longer the underlying machine backing the asset will be profitable for at the same 5% diff increase.  At the same conditions, the S5 will no longer be profitable to run after about 120 days.

So right off the bat, this contract will take longer to pay back the initial investment than the unit will be profitable for.  Of course, 5% difficulty is on the higher side of things lately, but I actually think it will be under a few changes we are about to see in October and November due to releasing of the S7 by Bitmain and whatever Spondoolies has up their sleeves with their new monster hasher.  Either way, its not giving me a great vote of confidence right off the bat for the V4.

And finally, based on my spreadsheet here...
https://docs.google.com/spreadsheets/d/1zbKKyXtW0vcfGDufk_UIRg_gAi0JzjsFwvB7LGj8bOI/edit?usp=sharing
The V4 contract has an APR of roughly 7.15%, which is right in line with V2 and about 5% lower than V3.

Conclusion: I have really liked the PACMiC's since they first launched, they have been a great sort of CD that have provided better rates than a normal CD and have allowed me to park my funds in them for some easy profits.  With V4 though, it seems less thought out than the other versions and presents a much higher risk that the underlying hashpower will become unprofitable to run before it has paid back the entire principal amount.  I will not be buying V4 contracts at the current offering they are being presented as.

First impressions suggest this contract is not as good as V3, and is more in line with V2.  Will have to run the numbers through a spreadsheet once I get into work to find what the APR would be.  They are claiming 14.1912% annual ROI for V4, they claimed over 25% for V3.

The V3 is looking closer to a little over half of that, so I would estimate V4 to be around 8% annual ROI maybe, just based off of a rough guess.

Either way, it doesn't matter as the S5 is at 60% maintenance, which worries me, with the current difficulty jumps we have been having, about how long it will continue to remain profitable.

Let me run some numbers and I will post here a little later.

I think I remember reading about the SMART miner awhile ago.  If you look at their website, they are offering 20TH/s for 2100 watts of power.  That is half the power consumption of Bitmains brand new chip.  I find it hard to believe that a company no one has ever heard of has somehow developed a chip that beats the leading manufacturer in the Bitcoin space, not by a little, but literally blowing their machines out of the water.

Contact the guy on Craigslist and ask to see the miner and see them in action.  I would not buy a thing unless he can verify in person that it indeed gets 20TH/s while using 2100 watts of power.  That sounds way to good to be true, and usually when it is too good to be true, it usually is.

EDIT: I am also fairly sure that the picture they are using on their website is a stock photo that many scams have used time and time again of an old computer, can't remember the name off of the top of my head though.  Also, not sure why they would mention you can plug a mouse and keyboard into it, that means nothing and shouldn't really do anything.  Also, have 2 Ethernet ports is a little weird.  Personally, just too many little weird things that collectively add up to equaling scam.

Nice, not sure on what that means though.  Certainly they are not vouching for the authenticity of Haobtc?

Link to where they partnered with Antpool?

I think the price is fair for the unit, for what it is capable of doing, but paying more than the device cost to have it shipped to me just seems wrong.

Shipping is too expensive.  Why pay more for shipping than the device actually costs.  The ones shipping to US residents should already be in the US and can be shipped out for 5 dollars max.

Very interesting development.  I will have to take a look at the wallet a little later.
