6) You are selling your "stakes" for 0.7 BTC each - what buyer should receive instead of his/her BTC?
the price of scrypt at Nicehash is low and you could get godzillions of those for 100k sat. And add staking to that. I doubt it would cost as expected by those who buy MNs at pre-sale. But those kind of risky investors knew the risks. It's theirs own fault and they're to blame
