My daughter asks, "Why 21,000,000 and not 20,000,000 or 10,000,000?"
Discussion
Because have a grandparent to.
The number isn’t really important. The fact that it exists is.
Tell her it's because of 21 savage.
"21 21 21"
Satoshi was a God or is a God. He's knowledge of the way the universe works and how math is intertwined with the universe like the fibonacci sequence.. its all connected to the universe
Tell her the secret lies in something called "floating point arithmetic" ... I'll leave it as an exercise for the reader. :)
great question "LOL"
Not sure what the right answer is.
But probably just because that's the total number when it starts with 50 BTC block reward and halving every 210,000 blocks for with 32 halving
So what I'm wondering are actually
1. Why block reward start at 50 BTC?
2. Why halving every 210,000 block?
On unrelated note. Why difficulty adjustment is every 2016 blocks?
Satoshi mined 1 million bitcoins straight away after creating it and then never moved it. So I guess he thought 20 mln in circulation was a good number and 1 million to mine in the beginning and not move until who knows when was a fair amount.
