Update
my big investor will buy 100M cell in 2 month
i confirm , 18MW will complete in this year
if not, i will buy back @ 0.000431btc(@250usd/btc)/cell (include pos) or 0.1 "new coin"/cell
thanks ,for support solarfarm project
Maybe an Escrow for the total refund supply at that value could incentivate people to trust in the project
