Taken in account the sheer hype that surrounds NFTs and similar extremely speculative stuff, the risk management of such a fund is
not going to be a piece of cake. If it was only for bitcoin, then the risk may be less.
Maybe the Bitcoin Fund could be backed by something more trusted like a Bitcoin reserve or even gold in the event of major losses
like a project turning out to be a scam or the crypto market going into a fall in demand.
Why would someone trust such a fund? If someone wants to buy NFTs they should do it on their own. Then they would have the freedom of selling it whenever they wish, thereby reducing the risk that such assets face. Face it, NFTs are short term high gain stuff, they are not for long term.
This would also need backing from governments, a problem of taxation also would exist - if they are selling assets. Quite a lot of problems to deal with. I dont see any "startup" taking such a bold step.
On the other hand, ETFs seem to be getting a renewed attention again.
