Yes , I know .
Since I don't know about the whole details about this but one of the my friend told me about this and explained me .
According to him the network of the Bitcoin will see all the details in the Bitcoin transaction that how much they mined and how much they needed to mine more .
Usually  there didn't airise any technical problems but still after having  people things that price may get more high or may go down sharply , so we should remain active whether what is going on .
The last halving was in the last year about mid of the year , and now I think next halving will the final halving and after that no halving and no more mining of the Bitcoin will take place .
