''I promise that all BTC holders will receive not only B2X in the ratio of 1 to 1, but also a proportional number of Satoshi Nakamoto`s Bitcoins as a reward for their commitment to progress.''

There's more then a million BTC mined in the first year.  How exacty do you want to redistribute BTC between aprox. 10.000 wallets which people have ?

What is the proportional number exactly in this case?

Satoshi’s bitcoins will be allocated in certain places like authoritative exchanges, etc. We will inform you as soon as we get an agreement with them.
Bitcoins won’t be distributed before the network start operating. It is more likely that it’ll take a while before the launch, not simultaneously but with the equivalent charge of 1: 1
