Correct - in fact (unless you were a speculator) you wouldn't want to hold onto anything in bitcoin for more than the time required to clear a transaction.
If you point out that it has poor usability for payment, well, it's actually a way to store your wealth. If you point out that the volatility makes it a bad idea there, well, it's actually a vehicle for speculation. Why would you speculate on randomly-generated numbers? Well, because it's so good for payment... or keeping your money away from the government... or... crap.
