The supply of new Bitcoins and Dogecoins is depicted in the graph below.
The Bitcoin inflation rate is currently higher than the Dogecoin rate, but it reduces sharply to a rate close to zero. It eventually reaches 0% in 2140, after which there will be no new Bitcoins.
There are currently 100 billion Dogecoins. The Dogecoin inflation rate is fixed at an additional 5.256 billion coins per year for every year henceforth.
Which inflation rate is more appropriate for a general-use currency intended for use for transactions of all sizes? I realise this isn't necessarily the stated aim of either currency.
Answerers should assume that the inflation rates are sacrosanct and can't be altered in years to come.
