there is no "point", but this currency is very young in immature. If we had as many bitcoins as dimes on the market and 99,9% of businesses would accept them, then you wouldnt see such a fluctuations. To me looks like Bitcoin is a huge win! Imagine if people are willing to put their dollars in it, knowingly being aware this roller coaster can run from $2 to $12 and back to $2, then imagine its popularity when we have enough coins on market and enough businesses are accepting them.
Kudos to first adopters!
