It does seem an interesting concept and until reading this post I was unaware of it. One of the things continually pointed out by crypto skeptics is the fact that we will see an end to inflation of value because of a set number of tokens in circulation for things like bitcoin. The kicked around argument I hear a lot of is that due to the set number of coins, potential for hoarding,etc. that we will see a drop off in use thus the store of value cryptos can be will begin to lose value. I don't agree with this of course because of the value that certain block chains hold simply on their performance capabilities as networks and the operating systems that can be put built on them. But a set interest increase with a guaranteed ROI seems a pretty neat concept so this post has certainly given me something to google and have a good old fashioned read on so thank you. Keep Steeming. :)
