The mining date of the last Bitcoin corresponds to 2140, assuming that performance would continue in a similar manner. After the last halving, the miners will win a block prize of 1 Satoshi. It should not be overlooked that the mentioned date range is theoretical and there is a high probability that it will not occur.
It is obvious that the last Bitcoin mining date given will occur if mining operations continue with similar performance. In other words, BTC price should increase and miners should continue to be profitable. The increase in BTC price for the continuity of the network gains importance for the motivation of miners after Bitcoin Halving.
