Also I'd like to understand why coins are moving until the end of rising?
They are moving because they are moving. The intention is not to develop a program, deliver it, then collect the funds as our reward. The intention is to spend the money developing the project. But it's your BTC to donate or not to donate, and if one of your criteria for doing so is "that the coins do not move until the end of rising" then please do not donate.
Please do not rely on BCI. All donations are recorded in the genesis block and, if in doubt, can all be verified manually:
