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?
Who said the mining plan is going to expire anytime soon or ever?
Actually on every halving the mining reward for the Bitcoin gets a cut off by the 1/2 like when the Bitcoin network started the initial block reward was 50 and after every 4 years almost more precisely every 210,000 blocks sets a halving event in 2028 the halving will happen at 1,050,000 Block and from the current block reward 3.125 bitcoins to 1.5 and so this loop will continue.
