I am really confused about the proposition of "cloud mining" or "cloud hashing" services. Let's take cex.io for example.
Let's assume you are not joining cex.io to speculatively trade GH/S <-> BTC and you aren't planning on spamming your referral link all over the place. Why would you ever use their services? I honestly don't get it.
Some statements from their site:
Cloud mining or cloud hashing is a brand new concept, which allows users to form groups (pools), where their joint efforts are rewarded with greater income, in comparison with individual mining with own equipment.
Now, everybody can earn additional income with little to no risk and frequent payouts.
Cloud mining with CEX.IO is an easier, more convenient and vastly more profitable way to get Bitcoins.
OK, this all sounds like there is some possibility for me to buy cloud hashing time and potentially actually see a return on my investment right? Looking at their own calculator:
https://cex.io/calc we can see an estimate of predicted investment VS return.
The current rate for GHS/BTC is .0850, so say I spend 8.5BTC for 100GH/S, their calculator shows that in the first month I will make back 2.39BTC, second 1.59BTC...etc until the twelth month when it has dwindled to .03BTC and is fast dropping. The most I ever make back is 6.92BTC plus a few specks of dust after 12 months as the return approaches 0.
WHY WOULD ANYONE DO THIS? Please I don't want to hear about trading of GHS/BTC, I realize that this is how people are using it to make money, but cex.io themselves isn't only focusing on this, they are selling themselves as a mining service that makes sense, and to me it makes absolutely no sense.
Here is a scam service idea that could make a huge profit: set up a cloud mining service that offers better rates than everyone else. People pay you BTC for GHS. You don't use this BTC for any hardware, you just sit on it, and you pay them out a diminishing trickle of their own funds that decreases as difficulty increases. If you did this right you would actually be giving people better value for their buck than CEX.io and still making huge profits. Actually, how do we know that cex.io or other operations are not doing this?
Can anyone convince me that the whole thing isn't a huge scam? I would love to be convinced. The fact that proponents of the services are constantly spamming around their referral links doesn't help much.
