My favorite aspect of crypto is that it's universal. I once went to Czech Republic and got gouged when I exchanged my euro for koruna at the border. I could have avoided it had I known more about the exchange rate but I didn't and I'm far from the only one affected. So being able to spend the same currency anywhere in the world would be amazing.
You can use Bitcoin to buy things electronically. So in this particular way the Bitcoin is like conventional currency like euro, dollar etc. which can also be used to purchase things electronically.The most important characteristic of Bitcoin and what specifically differentiates it from conventional money is that it is decentralized ..no one particular institution has complete control over bitcoin network. Many people like this feature because they like the fact that no large bank can control their money.
