What mathematical analysis proves that BTC created by 2009 with a fixed supply of 21million.
It's called a
zeno's paradox.
Every 210,000 blocks (approximately 4 years), the block reward will give half of what was giving in the previous 210,000 blocks. The first 210,000 blocks “extracted” 10,500,000 bitcoins, the next 210,000 gave 5,250,000 bitcoins and it goes and on. The 34th halving will cut the reward from 0.00000001 to 0.00000000 and thus, no other bitcoins.
Precisely, there will be 20,999,999.97690000 BTC.
Exactly right. SO because the halving occurs every 4 years with the mining becoming harder and harder the system was created such that the total supply of BTC only increases at a certain rate for 4 years and then drops thus controlling the supply.
Because the supply is set and it is harder and harder to get more BTC the value should grow in the same linear pattern. This is why it is advised to take advantage of bear markets to stock up until the next bull run where we know BTC would set another record.
