I recommend you to read the hive whitepaper for more details.
A little excerpt:
Current Allocation & Supply: Starting with the network's 16th hard fork in December 2016, Hive began creating new tokens at a yearly inflation rate of 9.5%. The inflation rate decreases at a rate of 0.01% every 250,000 blocks, or about 0.5% per year. The inflation will continue decreasing at this pace until the overall inflation rate reaches 0.95%.
This will take about 20.5 years from the time hardfork 16 went into effect.

Hive on!
I tried multiple times to download the whitepaper from hive.blog, but I failed. It always shows a error message "Access denied". I have no idea whom should I ask to address this problem. I hope the devs will fix the link as soon as they get noticed.
👌Thank you very much for this workable link. I will read the whitepaper for better understanding as per your suggestion.
