I can appreciate the desire to limit the supply but I am not a fan of 5% a year. It may as well be nothing in my opinion.
This kind of rate is for coins with 100 million+ in supply, not Hyper.
Lets not be too quick to keep the current mistake made in stake rates because its easier to leave it as it is. Again, I can see the reasoning behind the suggestion but the drop from 5% a month to 5% a year changes the coins fundamentals completely.
20% a year might keep me interested, 5%.. meh. I dont think i'd even bother, I just dont get any joy from obtaining meaningless stakes of dust in my wallet.
