so here is a thing now difficulty is 933,520,449,715,105,000.000 and network hashrate is 600th

if they sell 100K units network hashrate will be 85000th=85ph

to know difficulty of that 85ph we need to divide that number to current hashrate and multiply to current difficulty

so 85000/600=142   142*933,520,449,715,105,000.000=1.325599e+20 if we add this number to calculator we will get those numbers

keep in mind that bitmain sold around 150-200k D3 it wont be different for this miner too
