[nrdmtt]

Anyone has a copy of the old ToS?
Just to know what they have changed and why (hashfast related?)

[skuser]

old TOS are here:
https://www.cex.io/terms

New here:
https://www.cex.io/tos


...edit: and they seem to be completely rewritten so for now I am giving up to analyze changes...

[nrdmtt]

Code:

ROUNDING POLICY

For all financial calculations, CEX.IO uses a rounding policy which rounds to the 8th digit after the separator, [b]in the favour of the platform.[/b]



Example:

If you wish to buy 0.1 GHS per 0.0595678678 BTC

The amount of BTC you will be spending is 0.1 * 0.0595678678 = 0.0059567868 BTC

1) The system will take 0.0059567868 and multiply it by 108, making it 595678.68

2) Afterwards the system will pick the minimum integer larger than 595678.68, which is 595679

3) Hence, to buy 0.1 GHS - you will be spending 0.00595679 BTC



If you decide to sell 0.1 GHS per 0.0595678678 BTC

The amount of BTC you will be getting is 0.1 * 0.0595678678 = 0.0059567868 BTC

1) The system will take 0.0059567868 and multiply it by 108, making it 595678.68

2) Afterwards the system will pick the maximum integer smaller than 595678.68, which is 595678

3) Hence, to sell 0.1 GHS - you will be earning 0.00595678 BTC

finally....

i was looking my account an saw this

C A U T I O N:
If you lose access to your smartphone, or uninstall the app - you will not be able to login to your CEX.IO account.
BE SURE TO BACK UP YOUR 2FA CODE IN CASE YOU LOSE ACCESS TO YOUR SMARTPHONE OR THE APP.

How do i make a 2FA backup? no one knows when i could lose my iphone and that would be enought of bad luck.. :/

You can also generate back up 2FA codes from your Google account I believe.

[EFS]

Rounding Policy will be very good. Can someone summarize the differences of new TOS? I don't want to miss important changes.

Google Account has nothing to do with CEX.io, so you believe wrong.

Well, is quite sure that prices at cex.io are in real bubble:
I used mining calculator at http://mining.thegenesisblock.com/ with buying 100GHS at current price from cex.io for 4BTC (1GHS=0.04BTC), and I couldn't break even with higher monthly increase of difficulty than 32% per month, see http://mining.thegenesisblock.com/a/7908fc0daa
If used more appropriate increase in difficulty of 100% per month, I can break even after 6 months when I buy 100GHS for 2BTC (1GHS=0.02BTC) and after next 6 month the profit will be 0.04 BTC, see http://mining.thegenesisblock.com/a/2be83da502

I guess that market participants at cex. io dont use math. Any comments?

Fixed percentage difficulty increase month over month over month.
Maybe in 2020 the total surface area of Earth would not be enough for all the asic chips, needed to sustain that difficulty.

difficulty is adjusted and can decrease... what happens nowadays is that minining power keeps increasing so new difficulty is always higher. i believe it should break someday

People who use the Genesis block calculator do not realise that. They blindly believe that difficulty will increase to infinity by the same fixed monthly percentage.

You're missing the point. My 2FA program or app is Authy. Authy attaches each 2FA to an account, one of the options is my google account. I can backup my Authy App and it will restore when I get my new phone after I verify who I am. The one catch is that I think you have to have the same phone number(i could be wrong). ie after I bought my new phone I still had the same phone number so I just restored per the Authy apps directions. There may be other apps for 2FA

Don't get me wrong, I know the difficulty will level at some point in the future. Thing is that if it won't level in 3-4 months, current prices for GHS are too high (they are great for operators to resell uneconomical hardware to suckers and speculators on suckers). And since we don't see deceleration on the side of hardware yet, it is wrong to suppose that the difficulty will adjust any time soon: new more powerfull and relatively cheaper products are announced already throughout the 2014.

What I expected in answer is somebody, who show me numbers: I bought GHS/BTC at this price and after 6 months I broke even (no referals counted) in terms of bitcoin and now I am getting positive cash flow only - you see it was real investment and I am not a sucker.

That is different from "You can also generate back up 2FA codes from your Google account I believe."
The codes generated from your Google account are only valid for your Google account and other and Google associated services, that are protected by 2FA.

I completely agree that GHS prices are too high and one can't ROI.
My gripe was mainly with the Genesis Block calculator.
A better calculator is http://btcinvest.net/en/bitcoin-mining-profit-calculator.php

You are correct. The time based rotating response 2FA apps that are available (including the Google Auth app) cannot ever work with backup codes from your Google account. Those codes only work with Google services or external sites that use Google's backend auth service (Bitminter is one of these). Cex.io uses the time based app so you cannot use backup codes from anywhere. If you lose your device and you don't have the private key saved somewhere to allow you to setup the app again on a new device then you are screwed. To backup the private key just write it down or save it in your favorite password app. Another option is to screen shot the QR code or the key while it is still on your screen when you setup 2FA on the website and then save that somewhere but make sure it is saved securely!

Btw does anyone know why the total pool hashrate on the website doesn't reflect the Blockchain diagram?

https://blockchain.info/pools

Ghash.io and BTCGuild are shown with the same hashing speed, yet the former is above 4PH/s and the latter below 3PH/s.
