lol
lets say we just think about:
600peta = ~44,000 S9 antminers(42857.14285714286 more precisely if your not factoring in slight hash variance)
now the antminer are retail $2k.. but manufactured at ~$500
$21,428,571(more precise asiccount) cost to make 600peta (~44k asics)
now using simple numbers (yep im gonna round them and not be as precise so dont knit pick, and just read the concept)
if blockstream started a manufactring company using its $70m
they could have made lets say 132,000 asics ($64m)
sold just 44,000 at $2k ($88m money back in pocket($94m including unspend $6m) AND kept 88,000 rigs for themselves..
Yep they could have 1.2Exahash running and now have $94m cash.
rinse and repeat
make 132,000 asics. sell 44,000 at retail.
keep 88,000(176k asics combined total) and then have another $88m($182m combined in pocket) (2.4exa)
rinse and repeat
