-snip- for bitcoin in the future, of course, bitcoiners want to be better and accepted as a payment system because of course it will affect better prices. Buy and selling Bitcoiners do is just to take a profit because they know the very fast movement of bitcoin can be used as an advantage
In general it is, Bitcoin is only used as a commodity asset or for trading to take advantage of any price changes.

Bitcoin is currently still a speculative asset.
