This is where Bitcoin comes in as a reward from all that mining. Bitcoin is the compensation received when people contribute their computers to the network to help process transactions, helping maintain it. Hence, there is an incentive for more people to join in the Bitcoin network and improve its stability and security.
Much like how traditional gold was found after a lot of hard work by miners, Bitcoin is ‘mined’ and retrieved after every block transaction is confirmed by the computers. The halving event is programmed into Bitcoin’s code to promote scarcity, and fewer Bitcoins are mined every four years, making it more valuable.
