If you buy BTC and store it in your personal wallet, it is an absolute asset for its ownership in a personal wallet.
BTC 100% is yours
ETF is an Exchange Trade Fund
BTC assets traded and managed by the company
you only deposit and withdraw funds in fiat
bitcoins are not yours
so buy BTC and store it in your personal wallet
like you bought a cute green frog and raised it until it grew big
and the frog is yours
