I recently bought $500 of bitcoin with the intention of dollar-cost averaging over the next decade, as I'm told bitcoin will be worth much more in that time.
anyways I had an old coinbase account so I just went there and bought the bitcoin. but now I'm confused, because, isn't that bitcoin stored in coinbase? how is it "mine"? I see people on here talk about a wallet or something but if coinbase shuts down isn't that money gone? how do I actually "own" the bitcoin without relying on coinbase?
