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...
thats a bad prediction. you are looking at from very narrow perspective.
if the reward splits for miners there could also be a 100% increase in price. meaning that nothing has changed.
