The point being: BTC is a an abstract good, of no practical use except that of being transacted. Has whatever value the people are willing to pay for it, and has had a value in the tens of thousands for long enough that buying one with the intent of keeping it for a while is not such a stupid idea. I don't currently own any but there is a price at which I would buy one, and that price is many thousands of dollars... For an alphanumeric code in a distributed ledger.
