#bitcoin: started thinking where the 21 million and halvening every 210 thousand blocks comes from. This doesn't answer the question wholly (why 4 years etc.), but it's interesting anyway. Is there any better known explanation to this?

"Here's a mathematical explanation:

Calculate the number of blocks per 4 year cycle:

6 blocks per hour
* 24 hours per day
* 365 days per year
* 4 years per cycle
= 210,240
~= 210,000
Sum all the block reward sizes:

50 + 25 + 12.5 + 6.25 + 3.125 + ... = 100
Multiply the two:

210,000 * 100 = 21 million."
