Someone correct me if I'm wrong on these answers.

Q. esper Will be released in one weeks or two...after releasing new wallet/client
A. Yes in 1 week or more we can exchange old Espers for new

Q. exchange you speak is ESP for BTC?
A. No, Old Espers will be exchanged for new Espers NOT for Bitcoin. It will be exchanged at a 10:1 ratio so if you had ten you will now have one Espers. This is because it was decided that the initial or old Espers coin would have too many in circulation.

Q. the value will be the initial 0.00000001?
A. No, the market will determine the value. It is reasonable to assume though that less coins available will now be worth more but the exact amount is up to the market.

Q. After compiling, it enters the market normally?
A. Not sure how to answer but I'm thinking, yes.

Q. What I recommend doing with my ESPERs....change or await the launch after compilation?
A. My personal recommendation is to withdraw Espers to your wallet and wait for the developers direction on how to proceed.

Hope that helps!
