To expand upon this because I think it's interesting and not something that everyone appears to understand with how the blockchain works: those are effectively the same. Everyone's coins are distributed across the entire Bitcoin network, and everyone who has a copy of the blockchain has everyone's coins, but only those who hold the corresponding private keys for each address (public key) the coins belong to can use them. So if you don't control the private keys to your coins, you don't control the coins.
