The problem is that everything is based on the intrinsic value of bitcoin, you put examples with real objects and that have a utility in this world, but you forget that the value of things are given by people, so although for you bitcoin is worth nothing, that does not mean that for me the same thing happens, and if the price is falling is because there are real people who are losing faith in technology, but as long as you have a cumulus of followers and users everything will be fine.
