How often do you actually have cash? It's rare that I do! The next item on this list is money.
In my country paper money is used way more than you'd imagine. But I still buy Bitcoin, since I expect world to ... evolve. As simple as that.
Yea, this. Especially when talking about the non-US/EU/CN/etc powerhouse countries.
But regardless, investing in bitcoin is a bet that people
worldwide are going to need a decentralized currency with a solid monetary policy. We don't invest in bitcoin just because of the fact that everything is moving digital (I mean, PayPal and online banking are already digital for a while).
