Bitmain's 1Q18 financials showed $1.2B old ASIC inventory.
Aren't old ASICs still profitable at low costs? I wonder what percent of the hashrate this inventory would represent if turned on all at once. Feels like one of the last opportunities to 51% attack BTC.

It'd be cool to see a breakdown of that $1.2B old inventory: how much is non-S9 and how much is non-BTC miners? Bitmain invested a lot in Litecoin & Dash so not all of that is BTC. Currently it would take about ~$2-3B to achieve 51% hash rate in BTC.

Assume 1/3 of that inventory is non-BTC (IMO reasonable assumption based on Bitmain's LTC/DASH numbers), that makes their BTC ASIC inventory stand at ~$800mil. That amount of inventory *alone* is significant but not big enough yet to pose as a threat.
