For investors, this event was highly anticipated because the first 2 halvings were followed by a bull market, driven by the combination of higher demand and a reduced new supply of bitcoin. In technical terms, this mining process creates Bitcoin’s consensus mechanism, called “Proof of Work” — explained below. This scares away hackers and bad actors because “hacking” Bitcoin to get everyone’s coins would cost a tremendous amount of computing power, electricity, and money.
