talking for myself, i choose bitcoin because it is fast and easy to use and also the value of bitcoin. bitcoin value is growing more often which is a very good thing to me.
Because it has the same store of value properties that gold has, like limited supply and the fact that anyone can mine it. Not only this, but it also has properties that gold doesn't have, like the capability to be sent over the internet, and easily stored, in a safe manner, if you take simple precautions.
