Limited supply the best option for me. but i am not an economic specialist and i have one meaning, maybe we need unlimited suply of currency for regulation some aspects of economy
Unlimited supply is the same as fiat do not fall for it, economist are going to say that you need an ever expanding fiat to make the economy work but that is not the way things work, economist are nothing more than people in the government bankroll trying to stop bitcoin adoption by saying bitcoin cannot sustain the current economy.
