I have a question about signing with Trezor: as you may know Trezor refreshes your addresses each time so I am not sure how I have multiple BTC addreses with 0 BTC but somehow the Trezor knows that my seed has X amount of BTC even when my used BTC addreses are empty.

When I sign with a fresh address does BTR knows how many BTC I have?

Best,
Sanchi
