if you do the maths the very last bitcoin will be mined in approx, the year 2140.
At the 2032 ish halving the overall supply will be 99.21% mined. That's almost all enough for me. In less than ten years it'll be 98.5%.
It's easy to let mining slip to the back of one's mind. There's been a veritable torrent of coins arriving for many years and that's going to dwindle rapidly. It'll be very interesting to observe the effects as the production levels are something we've gotten totally used to.
Let's hope that fee market is good and strong by then.
Hmm, now I undestand why Satoshi that that in 20 years Bitcoin will either have big transaction volume or none - by that time most of the supply will be mined, so 20 years wasn't an arbitrary number. We can see now that halvenings strongly influence the long term price, and unless something unpredictable happens, in 10 years it will be very high, just like Satoshi said (I use the price instead of original transaction volume, because we've already reached its limit).
