well one of the benefits of bitcoin is that you can always sell any portion of bitcoin as you like (of course as long as that portion is meaningful not like selling 1 satoshi or 1000 million bitcoin!). but you can never sell a portion of your gold!
so if some day i have some problem i can just sell 2.456214BTC from my stash and solve my problem.
although i prefer selling anything but bitcoin because anything else is not going to rise big time so for instance gold has nowhere near the potential of bitcoin. a year from now gold is going to be pretty much the same but bitcoin will be worth a lot more.
