Well I'm talking very long-term, obviously. But there is a finite amount of bitcoins, even considering you can pay with uBTC and mBTC, everything is finite. If you are losing 1-2% of your total BTC is existence every year, eventually the value of the remaining mBTC will be so high that it will be a currency for the rich. Something for future generations to figure out, though. But we should remember the lessons of Y2K about not trusting future generations to fix all the problems we leave them.
