Halving will be the "end" for many minermen...
The strongest ones will overlive.
Who will spend cash for losing cash?
After the halving ...people will keep up...and the "give-uper" will then give oxygen to the survivors...
Mining hardware will be traded for low prices...
I use them to heat my house. It works out to be cheaper to heat my house with my miners then with them turned off and heating by my baseboard heaters. I will only mine in cold weather now. It has made me like winter more than I used to.
