When a user solves the problem in a block, that user receives a certain number of Bitcoins. The elaborate procedure for mining Bitcoins ensures that their supply is restricted and grows at a steadily decreasing rate. About every four years the number of Bitcoins in a block, which began at 50, is halved, and the number of maximum allowable Bitcoins is slightly less than 21 million. As of 2025 there were almost 20 million Bitcoins, and it is estimated that the maximum number will be reached in 2140.

Machines—called Application Specific Integrated Circuits (ASICs) built specifically for mining—can generate more than 400 trillion hashes per second. In contrast, a computer with the latest hardware hashes around 100 megahashes per second (100 million). Initially, one would only use it for digital transactions, but now it is used to trade almost anything online.
