For me i prefer using cash for my daily transaction activities because i do not buy or shop online.
Also because not all establishment here in us was accepting bitcoin as a payment also i dont like to carry huge sum of money so it does not really matter.

But for the security purposes and conveniency i prefer bitcoin. Its easy to cashout and also i could gain something from it if the price of it increase.
For me it become my bank. Which is really good especially it avoid trouble for other people if they know that you have a lot of resources.
I like how the system works.
