Aron thank you for the answer.
I bought another SFX.
But I expected PRE ICO to be more profitable against ICO, for example, by 30%. It would be fair.
Now it looks different but we have invested in PRE ICO with less information and more risk.

I read new documents (good) and I have a question.
Why old SHA256 and not new SHA-3? (sha256 device exits = high start difference)
Will the number of nodes be limited?
How can node weight be increased? (holding SFX?)
How can I profit from holding SFX?

Can P2pool be supported from the start? (contact http://p2pool.in/) (Classic pool = centralization)

Do we have a forum for Soferox?

I see many great features...

Sorry, for my English. :-)
