Having a share in Grayscale mini trust shows that the university has bitcoin, or what does Grayscale deal on. Or are you trying to say that Grayscale doesn't have any bitcoin too and claim to have. There are some people that cannot be in possession of their bitcoin and they prefer to keep it in the custody of third-party to avoid the stress of being their own bank. ETFs made so many adamant people to adopt bitcoin and such people will always entrust their bitcoin to ETF. If you buy bitcoin from ETF, you pay in fiat and if you want to sell your bitcoin, they pay you in fiat does not mean you don't own bitcoin. You only don't have control over your bitcoin without them.
No, owning a share in Grayscale’s mini trust doesn’t mean you actually own Bitcoin. You’re just investing in Bitcoin’s value. If you really own it, you’d have the key or at least the ability to withdraw it.
Here’s how it works with Grayscale: you send them fiat, they buy Bitcoin, and when you want to sell, they give you fiat back. So where’s the Bitcoin in that? As long as you don’t actually have it or hold ownership of it, you don’t own any Bitcoin.
