Well, that is part of the reasons why the price will skyrocket because the supply is limited. Just like gold. I think buyers and holders of bitcoin today will be mega rich billionaires in future once the supply declines
I hope so! I bought mine 18 months ago but ended up selling some, I really want to get back into the 21 million club, at the minute I only own half

you said you own half , so does that mean you have 10.5 millions of bitcoin in your purse? Wtf man , that is pretty big . or you only mean that you only own 0.5 or half of the whole one bitcoin ? if it is then dont be so sad because that amount is still big and will continue to grow bigger as soon as the totall supply of bitcoin will run out.
Re: Is it possible to have bitcoin shortage?
Yes it is possible , bitcoin mining is the one reason that bitcoins supply is decreasing . but that isnt a big problem at all , instead it is an advantage to all of us because the price of bitcoin will probably skyrocket as soon as the supply is also declining.
