In bitcoin, litterally the only way to get a return is for more people to come in and push the price up more. If bitcoin goes to 1c you cannot get that value back even if you were correct that the "fair value" was above your buy in price.
If bitcoin dropped too much, the network effect could fade to a point it will never be worth mining it again, or used again and some other coin can overtake its role. Much like myspace died after it lost its network effect.
Its completely different. The stock will not go to 0 because 1 cent apple stock would be a bargain.

bankers: let's try marketing this as "blockchain", see if anyone's actually interested or there's a viable use case

No blockchain-based technology has been able to demonstrate anything close to this sort of intrinsic value. The claims of being an alternative currency have not been fulfilled and show no sign of improving. What they call a "scaling problem" looks unsolvable to me.
