For me, I believe bitcoin will play a significant part of the financial system in the future. I just don't want to miss the boat.
Why do I have bitcoins you ask. To buy things of course 
Couldn't resist the 10% discount over cash that Newegg was offering, with 10.5 million products to choose from.
Dell did the same "Dell offering 10% discount when purchasing Alienware with Bitcoin".
Why would you want to pay with cash and end up paying 10% more, makes no sense to use Credit Cards or Cash.
Those days are gone
