If bitcoin mining still works after the latest halving, how much can someone invest in the mining of the bitcoin and how much bitcoin is it likely to generate before the mining plan expires?
If Bitcoin mining did not work after the latest halving, I am doubtful that why are you here?
Newbies in Bitcoin market join it mostly because of a Bitcoin halving, noise about it, and growth of Bitcoin price in a bull run after its halving. It's your main reason to be here, and it means Bitcoin mining industry still works, and works very well.
If miners don't have profit from Bitcoin mining, they would have stopped their mining activities already.
