Bitcoin issuance halves every 4 years, it's a geometric series. It's like the lily problem but in reverse. > Lily pads are growing in a pond, and the number of lilies doubles every day. After 30 days, lilies cover the entire pond. On what day did the lilies cover half the pond? The answer is Day 29. Very late on the timeline. With Bitcoin, we've got halving instead of doubling, so most issuance happens very early on the timeline. In fact, 99% of Bitcoin's issuance happens within the first 28 years of the protocol's life. Bitcoin was launched in 2009. So a mere 15 years from now, in 2037, only 1% of all bitcoins will still remain to be issued. Will 1% be sufficient to attract enough miners to properly defend the Bitcoin protocol from attack for the entire rest of its useful life? I have my doubts.
