Assuming you've got a 3) and will add it, I'll contribute: 4) General, undefined fear that something bad is going to happen when nodes choke up on a backlog of transactions. - - no specific symptoms are pointed at but presumably there is "pre-traumatic stress" at play. - - Bitcoin-based businesses are going to lose money, customers and potentially fail - - people will flee Bitcoin for another cryptocoin and Bitcoin will be left in the corner, collecting dust and memories of it will fade as SuperCoin with its big blocks becomes all things to all people. 5) Specific belief that the exchange rate will decline on network unreliability - - traders and investors will bid the price down, or - - traders/investors will stop speculating all together because even if their speculation is successful, they're not sure they'll be able to get their bitcoin out of exchanges, what with the broken network and all. - - The exchange rate reflects Bitcoin's value and not just speculation guided by a few large players like in other markets. 6) Belief that Bitcoin's "cargo" is about to be delivered by fate: - - see https://en.wikipedia.org/wiki/Cargo_cult - - the cargo is variably presumed to be a range of hoped-for events: an adoption surge, a speculative rally similar to (or bigger than) 2013, or a global financial crisis that sees Bitcoin become the safe haven of choice. - - for the cargo to be delivered, a "runway" must be built - the larger the runway, the larger the cargo delivery. If the current runway is not expanded, then the cargo plane will go to a different island and won't come to Bitcoin Island. - - it is short-sighted and, in a way, ungrateful of the "generals" not to expand the runway - it will be their fault that the cargo doesn't get delivered and all the island's people, no the whole ocean's islands, will suffer because of silly security concerns. - - some people have taken the blueprints of the airbase and are building a large airstrip elsewhere on Bitcoin Island, but nobody is helping them build that long and wide runway. Everybody wants to expand this moderate runway - even the renegades who started Big Blocks Great Success airstrip. - - The sacred site of No-Middle-Zero-Attack-Point is at the start of the current runway. To expand it the site must be destroyed, but some former generals and many people say: It doesn't matter, we want Cargo, not a small attack surface. Just blast it!
