I do not have any hardware or software.

I am looking to purchase a 10GHZ mining contract.
Suppose a 10GHZ 12 month Mining Contract is worth 3~4 Bitcoins,
is there any estimate or your past experience on the return in BTC after the 12 months ???

Is there any mining contract you recommend?

You can buy GH/s here : https://cex.io/r/0/Seccour/0/

0.1 the GH, and you can trade it when you don't want your GH any more.

Referral link : https://cex.io/r/0/Seccour/0/
No referral link here : https://cex.io/

I wish to know if there is any estimate for how many BTC a 10GH/s will return in a year. ESTIMATE, Historial

after that, yes I can buy GH/s there! thankyou

Nobody knows it depends on the how fast difficulty rises.  The cheaper the cost per GH/s the more likely you are to turn a profit but there is no guarantee.

Anyone selling you a contract is likely selling you something worthless.   Think about it for a second say YOU had 10,000 GH/s and they will turn a profit.  Would you sell them to someone else or would you just keep the profit.

Your best bet is to use https://cex.io because at least you can sell it back. I would throw my referral link up but I was beaten to it and just wouldn't be fair play. At least there you can sell it back and it is more than just a 12 month contract. Right now for 3 BTC you can get 30gh

The greater fool theory.   This is totally worthless garbage but you MIGHT (key word you might not) be able to pawn it off on someone even dumber than you to make a profit.

It is much better and cheaper than buying a 1 year contract.

@dnt, I was wondering the same when asic miners were released. Why would BFL sell? But, eventually I understood the difference.

Now, I had same doubt about cloud mining companies. I think, they just are sharing risk and profit with their clients.

Or selling at a price that ensures they will profit and their "customers" (suckers) have no possible hope of doing so.

Quite possible. :)

With the calculator of cex.io :

( No maintenance fee and no pool fee for their pool now )

I'm using this

http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=390928787.63809&dcosts=204&diff_mincrease=45&blpbtc=25&dhsmhs=10000&diff_mincreasedecrease=10&btcusd=200&dpowcon=&btcusd_mincrease=0&pcost=&calcweeks=32&dleadtime=0&action=calc#

here I get that the most I can earn from 10 GH/s is 0.65 BTC, but I spend 1.02 BTC right now to buy those 10 GH/s, so if cost per GH/s goes lower than 0.5 BTC I won't even break-even.

Then you should add around 0.037 BTC of maintenance fee for month starting november 1st, which amounts to 0.44 BTC per year, so you're going to earn 0.22 BTC after one year.

In the end your only hope is to find a greater fool who buys your 10 GH/s at a higher price...

spiccioli

Not for long, it's being introduced on 1st Nov.

It is economically absurd,

If the Miner has the GH/s why would he sell them? perhaps DeathAnd Taxes is right

Rigth on, so owning an ASIC mining rig is one way to get involved now. Unluckily I dont have the greens.

Good Bitcoin projects are coming, that I think is true

first - do you think this section (pool) is right for such question?
second - asking something like that you will get lot of link to cex.io ... and that is not because cex is so good ... that because of referral cex programm

I was reading this https://bitcointalk.org/index.php?topic=163741.0 (https://bitcointalk.org/index.php?topic=163741.0) today because I was asking myself the same questions. I found it interesting you may as well.

dont buy a 10 THs mining rig, cuz POI is to long. Ibelive after new ASIC miners come the BTC difficulty will increase faster that anyone could preditct

Definitively these companies put the risk on their clients, while these companies are profitable.

There is not sharing risk and profit at all

i agree with that, but they havr risk if they dont sell all ghs/s and if they dont get POI
