In my opinion, one of the biggest hurdles to greater adoption is the lack of on ramp or off ramp options.

Any new seemless on or off ramp experience will make more people aware of it, easier to hold, easier to liquidate. When easier to liquidate people will hold longer as they think they can convert it anytime in the future instead of a risky asset that you need to get rid of now.

Easier to liquidate will also mean more sellers will be willing to hold for a while rather than instant liquidation.

All these will also make the IBIT buyers rethink their strategy (pun intended) as they see others are using btc as money but their btc (if they have any) is locked in a portfolio account.

In other words all these mean another good step towards BTC slowly gaining acceptance as a parallel money (rather than a high beta nasdaq). It will be particularly popular with bitcoiner visitors to the US (or other international travellers) who will not have to worry about buying foreign currencies and dealing with alien looking papers.
