Don’t confuse MtGox with Bitcoin. Bitcoin is a payment system and currency that could change the world. It enables people to have trust in a decentralised public ledger that verifies ownership. It enables the free (or very low cost) and instantaneous transfer of funds around the world. It renders banks redundant for such transfers. It eliminates chargebacks. And more. MtGox is (or was) a poorly run exchange that ran into all kinds of problems because of its own internal errors.
