During the last years, I have calculated the amount of bitcoins created from the first block to the last block per year. Numbers from 2020 are estimates based on the **Assumption that we will add 54,000 blocks per year**, which would be the result of today's block interval rounded to thousands, or an average block interval of 9.73 minutes. In exactly 10 minutes, we would expect 52,500 blocks per year.

2017 update:

It turns out that 2016 had 55,184 blocks (or an average block interval of 9.51 minutes), so with 54,000 blocks it had underestimated in 1,184 blocks. Therefore, inflation rates could be slightly higher than the estimate provided here, if that interval remains accurate. New estimates were still calculated with 54,000 blocks per year.

2020 Update:

2017 had 55,928 blocks, 2018 had 54,498 blocks and 2019 had 54,232 blocks. It seems that we are finally getting closer to the estimate of 54,000, so I continue to use it for the estimation of future years.
