I don't see why Bitcoin can't continue exist long term with current sentiments. Some factions think it's a store of value, others say it's a security, or at worst, a money laundering tool. All of these same arguments can applied to paper bills-- and these arguments won't go away in 10, 20 years. There is no prevailing narrative for what it "is", though actors are certainly attempting to craft one. Sentiment in public markets will shift over time, up and down, sometimes dramatically, but nothing's convinced everyone we should all give up on Bitcoin --even after those dramatic falls-- and until that day, it has economic value. The US Stock Market survived the Great Depression, Bitcoin can (and did) survive the 2018 bubble.
