Earlier quoted context omitted.
Real markets, or the companies within, make something that people need. They have equipment, customers, etc. Maybe they are important enough that the state has to bail them out. Maybe they get restructured or merged. Anyways, there is some kind of floor to which they can fall, and which will catch them. What kind of "floor" is there for crypto? By definition it is not tied to anything non digital? Right?
A company can go out of business and cease to function. What would cause the Bitcoin network to cease to function? There will always be a market price and it will fluctuate. But the end of Bitcoin? Would be like the end of BitTorrent, not gonna happen.
Not a finance expert, but I disagree with what you're saying:
There's a feedback loop between:
1. The price of BTC, which depends on people's willingness to mine it (without which, BTC doesn't have security).
2. The willingness to mine BTC, which depends on the price. Why would you mine BTC if you're not sure whether you'll be able to sell it for more than you mined it for?
A decline in 1 can trigger a decline in 2, which can trigger a decline in 1, which can trigger a decline in 2.
BTC can have an end. Oh, and BTC is not like BitTorrent.
