Does Coinbase own my crypto?

As a cryptocurrency investor, I've often wondered: does Coinbase, one of the leading cryptocurrency exchanges, actually own my crypto holdings? The thought of entrusting my digital assets to a third-party platform always brings up concerns regarding ownership and security. While Coinbase provides a convenient platform for buying, selling, and storing crypto, I'm left wondering if they essentially "own" my cryptocurrencies. Does my digital currency remain in my possession, or am I simply leasing access to it through Coinbase's services? Clarifying this ownership question is crucial for understanding the risks and benefits of using such platforms.
