Where does the 99,800,399.2 CAT floor come from?

What else is taken on top of the rate?
The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending CAT, and that one goes to the blockchain, not to us.

Which network will BTC arrive in?
Bitcoin leaves in its own Bitcoin network — a plain BTC address is all you need.
What if the rate moves while I am paying?
The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the CAT to BTC rate do this month?
The month came in at minus 22.58%. Low 0.000000000021, high 0.000000000027, middle 0.000000000023 BTC per CAT.
