From a quick reading of TOS version 2, and maintenance page, CEX is changing GHS maintenance fee calculation for a flat monthly tax of $0.26 per GHS. First analysis: seems better! At least, seems fair enough. Of course, when mining does not result in blocks, user will still be charged the maintenance. So difficulty will tell profitability. All in all, I think it is more easily understandable to the user.

We ll see how it works. So far, congrats CEX. Changing was needed.

PS
Trading fee is also here now, TOS v2, but in a 1st glance of my existing orders I didnt see a % value.
