Ok, now the dev says that if I want to make early payment I need to pay extra 0.05 BTC, where was it mentioned before.

Dev,
you send my collateral BNT first to my account, so that I can dump at a reasonable rate now. By the time you unload your premine, this coin will become worthless. If I don't get my BNT within the next 2hrs, you can say good bye to your 0.2 BTC.
