i created an account on CEX.IO afew months ago.
AS a starter recently i managed to fund and charge my balance on GHASH.IO with Bitcoins and i'm planning to purchase Gh/s and start mining my bitcoins, the overal site is kinda complicated to me so, please can u guide me how to purchase my Gh/s cloud service and start mining my Bitcoins ?
thanks for reading my reply and thanks for ur support, quality and patient.
I do you one better and give you very valuable advise, Ghash.io/CEX.io is a PPLNS pool, meaning you get paix X amount on N shares, or so many shares at the end of a block, because of this purchasing GHS is useless sometimes as the reward is smaller then the fees associated with their cloud GHS. What this means is simple, they charge you maintenance fees on every single share you provide in each block but only pay you for a certain amount of shares at the end of the block. the longer it takes to solve a share the higher the fees and the lower the reward will be.
If you still do not understand I will try and break it down in numbers for you (these numbers are not exact but a representation of what they are doing to screw us over) if you processed 1,234,567 shares and it costs 0.00000001 per share in maintenance fees but it takes 2 hours to solve the block and you get paid for the last 15 minutes of submitted shares only. In that last 15 minutes you only processed 154320.875 and you got paid 0.00000002 per share on thieir PPLNS system your reward would be 0.00308641 but your fees will be 0.01234567. leaving you with a loss of 0.00925926. and this is how their system works but the numbers are not quite that high, there still is a loss and sometimes with high enough GHS it will be substantial. Basically the more GHS you own the worse off you are as far as mining for them goes.
Now in order to make a profit you need short blocks onlyso if you would work for 15 minutes and process 154320 shares you will be charged 0.00154320 in maintenance fees but your reward will be 0.00308641 giving you a profit of 0.00154320. I showed an example including 50% fees a lot of miners are saying their fees are actually higher at 62% so this really hurts us. In addition the fees do not equal the power they say the fees are paying for, they are making a profit even on the electricity they say they are charging the fees for.
You will also nbotice your GHS you buy from them does not work every single shift but rather works 2.2 times as much one shift and not at all the second shift again incurring unneccessary matinence fees on 2% of GHS you do not actually own. They have a very nice system in place for their pocket that does not always benefit our pocket.
SO all in all DO NOT get GHS from them
its ok when you have a lot of 15 minute blocks and 20 minute blocks its the 1 hour and 2 hour blocks that hurt you, 1 a day is enough to mess up your profit exponentially, and they have more than 1 a day
