Coins being scarcer means nothing without demand.
Let's just hope in 2 years there is a breakthrough in adoption.
Hopefully there will be much more demand in a couple of years time. I think there will be.
So many things in science fictions have come into being. God knows what role bitcoin will play in future human life.
I think bitcoin will see a several fold gain within 2 years, within five it will have gone to a few thousand and hopefully within ten it will be very mainstream and the price will be ridiculous. Of course this is all wishful thinking, however.
