This differs not only from the general model, but even from disposable hot wallets. Disposable hot wallets end up with very few addresses that have Bitcoin in them. But Coinbase's hot wallet has not just a handful of addresses with Bitcoin, but many addresses with Bitcoin. the number of Bitcoins that each such address has is not large, but together it adds up to a large amount. This way of operation puts a high demand on Bitcoin address management, which is probably not the case with other exchanges. Reason for this approach: The addresses in Coinbase's hot wallet address library begin with bc1 (using the Bech32 encoding, prefixed with bc), the vast majority of addresses are one-time (only two transactions, one transfer and one (transfer out), after which it is never used again. The Bitcoin you get from your coin wallet will be transferred to a new bc1 address in this repository. When a coin is withdrawn, it is transferred from this bc1 address to a new bc1 address, and so on. This method basically eliminates the possibility of algorithmic mining, but it's also extremely secure.
