Bitcoin mining industry spend about 140 TW/h yearly

this is aprox 16 GW per hour.

How many hashrate can represent this?

Currently is 360 EH/s but could be the DOUBLE OF THIS

why? Because the most efficient miner is the S19 XP with 140 TH/s for only 3100 W per hour.

Do the maths, 16 GW / 3100 W = 5 M of ASICs S19 XP

This represents aprox. 700 EH/s

We are at the midway of that.
