yes, this is what an ETF means, they have to aim to hold the stock that they have users claiming to, minus the margin, and i'm pretty sure that ETFs are allowed to fractional on this shit, they don't have to have that balance exactly within some time window, idk what that is, but it's all bullshit, they only hold enough to disburse to the withdrawals most of the time, and they are not really held to the same standard that you and me are if they don't have it when it's asked for, so eventually it is a bank run yawn

really, i seriously doubt they make different rules for bitcoin ETF than any other

the biggest difference with bitcoin is that they don't even have to be an ETF, they can be a bank, the asset has no physical substance and a negligable time of delivery, so it's retardation from the very base of the idea
