Inflation is bitcoin supply is quite high, and will increase for the next years to come. Supply of money is also a matter of velocity, or speed, of money flows. Keep that in mind.
Now that is a magnificently bad explanation :-)
Currently the growth of Bitcoin supply is a little less than 4% and will decrease for the next years to come. Supply of money is deterministic and not a matter of velocity, or speed, of money flows. Keep that in mind.
