Alright, just off the top of my head, I'm assuming 650-850k, but can recalculate everything to dcheck. 200x200x50 totals 2million blocks, which I estimated would take over 100 hours of non stop mining

 

I'm factoring in blocks mines per hour non stop into the equation. At 25 cents per block, i'm earning roughly 4-5k an hour, which I could triple or quadruple easily in the mining world
