and you need to know that there will be miners which will dumping this coin without any profit, spending more for electricity than earning on mining.
Let's see how the mining will be done, i think will be fair.
some facts:
total value of ipo about 350/400 btc, : 100.000.000exo = 1exo = 0.000004/0.0000035 BTC right now, i highly doubt that will be dumped to a lower price at least.
mining:
50.000.000 x 6 months (180 days) 1 block every 10 min = 1929 exo x block = 277776 a day spreaded over N miners....
Your math is a bit off, though the result is close.
100M total, but only 42M From the IPO. (23.5% stage 1 and 18.5% stage 2).
I don't know what's in escrow, but it's about 150btc from direct investment. Probably another 50ish from escrow.
Roughly 476 satoshi / 1 EXO based on these figures.
