We have seen on the richest addresses list that bter sends the funds of all users to a single address.
Thus they would need to have a function in their software to calculate the balance of each user at block 32k.
Maybe you should start by explaining the PTS system, and tell them that they are able to redeem a lot of MemoryCoin. When they do, they don't have to forward them to the users, but as a service could offer to their users to redeem on request. Or they add it to the users' balance - what a great surprise would that be for some.
Don't have a lot of time right now, but we can work out a message here together if you like. When they don't just keep the MMC for themselves it's a nice pr opportunity for bter and maybe brings some new people to MMC.
