I agree, unlikely but not quite zero. As is the general rule with complex things. But again, until a show stopper is found, I would say that bitcoin will never be popular as a means of payment. People would increasingly use it as a vehicle of savings. Once it has reached some point of "maximum adoption", it would start behaving exactly like post-1973 gold. It would still go through periods of speculative enthusiasm in which allocation to bitcoin increases, followed by periods of aimless grinding in which it drops again. It wouldn't follow CPI tick-for-tick, but over very long term periods, it would be nicely mean reverting vs cycles of general price levels and financial market prices. And as such, in terms of bad forms of money like government currencies, it would ultimately just keep rising forever. Or at least never go to zero. So people who say "bitcoin is a bubble because it's not used much for payments" would be wrong. It's going places exactly because it's not being used much as transaction money. And so, as Nobel prize winners would move up from the step of calling it a dangerous bubble to the step of decrying it as a deflationary threat, I predict no end to their criticisms.
