Don't modify POS% let it at 100%. Hi POS hi supply were a problem when you had the 1 sat treshold on BTC market but it's not 2017 anymore and SHND is below it for quite some time already. DOGE markets are now healthy so there is no problem to let it as it is. It wille ven erase its uniqueness think about it. Easterners like Japanese especially likes big supply.
The 2B cap still need a solution.
100% POS reward is not sustainable, number of coins will increase exponentially. Those who don't want to mine/stake will eventually loose value against the miners/pos community. Ultimately coin will be dead again if pos% is not decreased.
and new people are not here because of big supply, they are here because something new and big is gonna happen (I suppose) with the appointment of new dev and expecting coin burn or hard fork.
