Bitcoin is better that "real money", Bitcoin is money managed by a decentralised infrastructure that cannot be stopped by anybody. The only way Bitcoin can be stopped is if the entire world's power supply is cut (not even that I believe will work because there are a number of projects that run on clean energy nowadays).

So why is Bitcoin better than "real money"? With Bitcoin you'll be able to travel anywhere in the world and you will be able to shop with your BTC without any currency's being exchanged for the relevant country's fiat.

Instead of having numerous centralized banks managing the world's currencies Bitcoin is a "single currency" that can be used anywhere in the world.

Just my thoughts
