When you have bitcoins on a Coinbase or similar account, you don’t actually hold bitcoins in a technical sense. It’s like having a tech-savvy friend hold your bitcoins. Coinbase, or your friend, has the private keys to the bitcoins (actually to the UTXOs) you have deposited, and you trust them to eventually give you back your bitcoins by sending an equal amount of bitcoins (but probably not the same original UTXOs) to whichever address you specify.

Keeping your UTXOs in a wallet of your own is another thing entirely. You hold your own private keys and are responsible for keeping them secure.

Kind of...  but I understood your explanation the best Smiley  I guess maybe since I don’t actually use them for anything other than investing then none of this really applies to me is what you’re saying? But if I buy things or do other things with them, then the keys are essential??

I mean I’m sitting here thinking, reading all of this research about how coinbase is almost virtually unhackable, because they store the keys in an underground vault that’s inaccessible and has never touched or will touch the internet.  But if what they are storing is not needed to cash...

OK so after reading everyone’s replies this is what I get out. At the point where I buy and keep them at Coinbase  or send them to another Coinbase account the keys are never involved. But if I decide to send the coins to another exchange, then the actual keys are in fact sent at that point? So that means if somebody were to hack into my account and transfer the coins to their account, then at that point the keys ARE sent along with it?

So my understanding is not correct and my “keyless” concept ONLY applies to me keeping it all local on the Coinbase exchange, correct?

Then if that is all correct, the only question is why does Coinbase tell me I cannot get my keys?  That can’t be true then and that’s what made me think the coin‘s were not sent with the keys because they say they’re not available to me?  But they are available to absolutely anyone else when they are sent?
