Because the companies make MORE profit by selling to you at inflated prices. These companies are just as capable of doing the mining calculations as the rest of us. They've spent quite a bit of time analyzing things to come up with a price point that minimizes their own risk, and transfers it solely onto the shoulders of the consumers. Let's look at the latest offering from Bitmain/Hashnest. They are offering 0.00135BTC per GH/s, and $0.0032422/GHS/Day in maintenance fees. If you break that down, you'll see it translates into the same thing as purchasing an S2 for 1.35BTC and paying somebody $98.62 a month to host it. In order for you as the consumer to have a prayer of turning a profit, the network difficulty adjustments must be 5% or less consistently at current USD->BTC conversions.
You are of course entitled to your own opinion, but that is not reflective of our business model.
We operate the same way I've run businesses over the last 20 years, that the economies of scale of large operations mean we can divide it down into chunks that make sense to other smaller people, and essentially arbitrage the fact that whilst you could do it yourself, it doesn't make sense.
Having built, bought and run data centres with over 10MW of capacity in the last 20 years with thousands upon thousands of servers in them it's a business we know well.
It's just like in the early days of the Internet you could run your own mail server to do that funny 'email' thing. Then people like us built massive servers, sliced them up, and sold them to small business and end users and eventually no-one ran their own mail server any more because the total cost of running them didn't make sense.
This is the game they play, and how they transfer that risk to you. They are betting the difficulty adjustments will be greater than 5%, and also that the fiat->BTC conversion does not inflate dramatically at present. By purchasing such a contract, you are betting against the house and hoping that either the difficulty adjustments stay absurdly low, or that BTC increases dramatically in value at the beginning of your contract and then continues to trend upwards throughout the timeframe of your contract.
Again, we don't agree.
We are just taking delivery of our Neptunes which take around 1500W at the mains. If you run one of those in the UK at 12ppkWh the electricity bill for the year is $2600 for 3TH, and you would have paid somewhere around $9995 to be in a position to have that kit now. Even if you assume that price is half because of the KNC 2:4:1 offer (which ignores the fact that the free one is some weeks/months away) compared to doing it yourself we feel our costs are highly attractive, so lets be generous and say $5k for kit, so that's a total year cost of $7200.
Even if you can get power at, say, $0.10/kWh somewhere else in the world, then that just means your electricity bill is $1300 per year for 3TH, so let's say $6300 including kit.
So '1TH' worth is somewhere between $7200/3 = $2400 and $6300/3 = $2100.
Of course this ignores the following
- Outages (we guarantee service)
- Low Pool luck (we guarentee 100% luck with 5% pool charge (=95% luck with no charge)
- Variable hashing rate over time (we give you exactly your %age of the global hash rate)
- PSU capital cost
- Cooling cost (maybe you can get away with it depending where you live)
- etc. etc.
and the cost of the space (but if you are doing it at home, maybe that's free)
Other cloud mining providers offer a fixed rate contract. They're doing the very same thing, except charging you everything up front instead of amortizing the "maintenance" fees over time. As an example, let's look at MegaMine. They are charging $3100 for a 12 month contract of 2TH/s. That's actually a bit cheaper than the same from HashNest (2TH/s at HashNest = 2.7BTC@$479 + 197.24*12 = $3660.18). Regardless, the outcome is the same: you are betting against the house (in this case, you're betting that MegaMine is wrong in their predictions).
1TH is $2100 for a 1 year contract. $2400 for a 3 year contract.
So we are the 'same' as the $0.10 case, and cheaper than the 12p/kWh case of the UK, with many benefits above the DIY.
If you take the 3 year view, then it's no competition. 1xNeptune in the UK over 3 years (keep the $5k for kit) is $12800 all in, we are $2400.
So are we mad? No, of course not, because it's like selling a 1 year or 3 year's worth of cloud storage on the same basis. Sure, today 1Tb of hard disk costs 'X', but in 3 years time it will be probably 1/10th of X - and the overall storage system will have been upgraded at least twice so the costs all work.
Similarly 3TH will cost you around $5k in hardware, but in 1 years time it's going to be a fraction of that, because we'll probably be buy 16nm or smaller kit running at 20-50TH 'per box' so a 1TH slice of that will be very cost effective. Because of who we are backed by we can therefore take these 2/3 year views, which is another reason we don't just mine ourselves, because then we'd need to take those views on both BTC:USD and global hash rates. We might be good, but we aren't that good, but one thing we do know is Moore's law does apply to hardware, so that's a good bet.
So how can we do this. Simple, our costs are much lower because we forward buy massive amounts of kit, we have Hydro power, we host in the middle of nowhere where it is cold, and we have built huge automated systems that keeps everything alive and working all the time.
Just like those email servers all those years ago. Then web servers. Then Internet transit. Then voice minutes. Then [insert your favourite telecoms arbitrage analogy]
So, why do we sell contracts? Because we believe that:
a) we can better the pricing that people can do it themselves when they take the full costs into account (of course if people get free electricity, or just run a miner in their bedroom then that may not be right)
b) Our scale gives us inherent advantages, and by offering a compelling product then we can build a sustainable business that enables us to continue those advantages
c) We don't have to sell the bitcoins generated, which helps everyone as distributing amongst end users means they will use a variety of methods to monetise them (including spending them as bitcoins, not fiat)
Yes, customer's are taking a risk, but then so are we, because who actually knows what is going to happen in a years time, never mind 3 months. This again is no different that buying any sort of service from a large company - sure, you might be able to wait a few months and get those hard drives, processors and everything else that makes up a server to run your email cheaper, but then there might also be a factory fire which pushes the costs up massively.
As I've said on this thread and elsewhere, we aren't interested in making any wild claims about what may or may not happen, we just build the best possible service we believe we can, price it at what we believe is a compelling price point, and then provide as much information that we can to ensure customer's can make an informed choice.
Hopefully we also provide a balanced view across the views, because given the examples where our costs are below kit+electricity, if it's "mad" to send money to us, it's "madder" to buy kit and do it yourself.
Thanks for informing the debate though.
