I think that paper money will always be popular and in demand, because it is much more pleasant to feel bills in your hands than to constantly worry about a possible hacking of your card or electronic wallet.
But it's even more pleasant going to sleep knowing the fact that bitcoins has increased by $300 and probably would increase more in the coming years. Even though we don't feel it, fiat is inflating heavily. We all know that everything that's not scarce will have a zero value. The government literally just print out money whenever they need it while everyone else has to go to their shitty job for 8AM to 5PM everyday and do overtime just to get some more money.
It will come to the point when fiat is too many that your currency isn't worth that much. You'd think that the commodities are becoming more and more expensive when it's just your currency devaluating.
