> Ethereum has addresses just like Bitcoin has addresses. The point is that Bitcoin actually doesn't have addresses/accounts. I think you are modeling this distinction as whether people clump all their money together into a single address/account or use a "wallet" of them (maybe all derived from a single key), but Bitcoin is way more abstract than that: there is no concept of an "address" at the level of Bitcoin itself... that is just a fiction created by an extremely popular way people protect money on Bitcoin. You might also note that Bitcoin tends to talk about different address formats (such as p2pkh), which often come from not merely different ways to serialize the keys but from different ways accounts have been protected with different scripts. In Bitcoin, you can have money that is owned by "anyone who can answer my math riddle" and that's that: unlike in Ethereum, it isn't that the money is owned by an account with an address which has code to restrict access, but the money is a little pile and the most universal "address" you can talk about is the script itself.
