Yes, I understand Bitcoin's monetary policy. The supply of Bitcoin and the amount of new Bitcoin mined each day is very simple and transparent.
For the first 210,000 blocks (approximately 4 years), 50 Bitcoins were mined in each block (each block is created approximately every 10 minutes). After that, up to the next 210,000 blocks, this amount decreased to 25 Bitcoins. Then 12.5, then 6.25, and now it is 3.125 Bitcoins.
This "Halving" process will occur 32 times, and by the time it is complete (i.e., around 2140), a total of 21 million Bitcoins will have been fully mined. After that, no more Bitcoins will be produced. Miners will only earn from transaction fees.
