What do you say to this conspiracy theory: the currently smoldering BTC civil war can lead to a fork.
In the fork case, self custodians are safe; they then simply have twice as many in two branches.
But the ETFs have reserved the right, in the case of a fork, to decide themselves on which branch the ETF holders have a claim.
That would be a gigantic, legal robbery and an extremely strong incentive to fuel such a civil war.
soooo...
