Well for me, Bitcoin is not just a digital currency used to pay for a variety of goods and services. Although physical forms of Bitcoin exist, the currency's primary form is data so you trade it online and make it grow or trade with other alternative coins like Ethereum, Litecoin and etc. , peer to peer, using wallet software or an online service. Bitcoin is cool, but the underlying technology behind it the blockchain is even cooler. Turns out, having a method to record data in a way that cannot be tampered or deleted is a good thing. It is also a cost-effective method to store information. That's why I prefer bitcoin, just like saying I prefer the substance rather than the form.
