If the token is already in my wallet, what determines whether I can use it?

I used to think that once an asset was in my wallet, the main question was simply whether I controlled it.

But bStocks made me separate two things.

I can withdraw a bStock to a compatible BNB Smart Chain wallet and hold it in self-custody.

But holding the token doesn't automatically mean every application can let me use it.

Third-party platforms and DeFi protocols integrating bStocks are responsible for enforcing geographic restrictions.

Binance also provides a country-eligibility endpoint that integrations can use to check whether a user is eligible in a particular jurisdiction.

So there are two different questions:

Do I control the wallet?

and

Am I eligible to use the product here?

That's the distinction I find interesting.

Self-custody changes where I hold the asset.

It doesn't automatically change where the product can be used.

So instead of asking only:

“Is the token in my wallet?”

I'd also ask:

“What determines whether I can actually use it?”

For me:

Wallet control ≠ product eligibility.
