Very interesting, then in a few years what is the maximum number of coins that can be reached?
The current supply is 17.05 million, including all the unclaimed coins. The actual amount of claimed coins and generated BTC2 in circulation is only a tiny portion of that.
About 400k BTC2 is generated per year until the maximum supply of 21 million is reached. So with the consensus rules as they are, that will happen in 10 years.
