The number of bitcoins issued is halved roughly every four years.
In the future this number of releases will be small.
Why not consider a fixed low interest rate mechanism to ensure that Bitcoin is more suitable for current economic activity?
For example, if you hold 1 bitcoin in an address, you will be rewarded 0.02 bitcoin after holding it for 1 year.
Interest is calculated and paid every year or before you will pay to another address.
So you understand the whole concept wrongly...
If there is something called interest rate then who is going to give that interest and how that it will be created? So if there is a mechanism which creates bitcoin out of nowhere then its inflationary right then how can you say it is a solution to fight deflation of having.
