In addition to monetizing, which is excellent and correct, I would suggest some alternatives. If you wish to carry forward the metaphor inherent to Bitcoin (that it is a digital coin made of bits) you could go with the following:
The act of making coins from metal is coining or minting
Early coins were either cast or struck. Casting was done by pouring molten metal into molds.
Other coins were struck with coin dies made by professional engravers. A planchet or flan (a coin blank) was placed on to the coin die for the front of the coin, and a hammer with the rear die was used to strike the planchet to create a coin with separate images on both sides.
Over time, advances in technology improved these techniques. Screw presses, mills, steam pressers, and eventually electric roll presses have been employed.
