Lets get something straight, Bitcoin is sort of a bubble because no one uses it as money. But it could be used if we close the secrecy gap.
While shitcoins can be used in secret, you cant really pick up the drugs in secret. So what you do i send a submarine to pick them up from another submarine, all underwater, and then it emerges tens of miles away at a remote location only you know.
Non-speculative demand for a real product is what bitcoin needs to have a stable, intrinsic value.
