That's the reality.
Only it's not. If it were so, we'd have Intel miners on every house.
Do you have one?
3 months ago the Bitcoin mining revenue wasn't a billion dollars a year. So no.
You're misunderstanding, also - it wouldn't be an Intel miner. It'd be an Intel
ASIC - the actual miner (PCB, cooling solution, PSU, etc) would be assembled by other companies (or enterprising individuals), and those entities would be Intel's customers.
