I'm trying to guess the number of existing VST.

I think the number of tokens will be 1.000.000.000 as the project claim to be a $1b value project.
200.000.000 tokens for Vostok 1 at $0.6 ($0.6*200.000.000 = $120.000.000)
100.000.000 tokens for Vostok 2 at $1.2 ($1.2*100.000.000 = $120.000.000)
100.000.000 tokens for Vostok 2 at $1.6 ($1.6*100.000.000 = $160.000.000)
We have 400.000.000 tokens (40%) to be sold for a total amount of $400.000.000.
The remaining 57% and 3% (60%) airdrop represent the $600.000.000 left, so $1b.
I'm only speculating

edit: If I'm right, then $1.6 and even $1.2 will be very expensive, and if the price is above that, it mean that Vostok is in the CMC Top 10.
