Do I own my coins on Coinbase?

In the realm of cryptocurrency, the question of ownership often arises when dealing with platforms such as Coinbase. The crux of the matter lies in understanding the distinction between owning the coins outright and merely having access to them through a third-party platform. As a potential investor, I'm keen to clarify: Do I truly own my coins on Coinbase, or am I merely entrusting the platform with their custody? I understand that Coinbase facilitates transactions and provides a secure environment, but does that mean the coins themselves are legally mine, or are they technically under the control of Coinbase? Clarifying this ownership structure is crucial for me to make informed decisions about my crypto investments.
