I'll take non-physical BTC coins any day over fiat.  My BTC are very secure, nobody knows I have them, I can access them on any computer anywhere in the world.  You can't steal something from me that you don't know I have.  I can cross international borders without fear of any customs agent, etc.....  I could literally disappear into thin air and the only thing I would need on the other end is a computer and my stash would be waiting there!  The feelings of control are amazing where BTC is concerned.  Sure, what will they be worth in a few years is a question, same with my stock portfolio!
