You never had to buy the BSQ token to use nostr:nprofile1qqsgqfapsalnnesrmt7xxfu7qp95akwlscw33n5pm8zrclt3xhdg7egprdmhxue69uhhyetvv9ujucnfw33k76twwpshy6ewvdhk6qgawaehxw309ahx7um5wghx6at5d9h8jampd3kx2apwvdhk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhscyvr9p. You could buy it if you wanted a 60% discount on the trading fees paid to the DAO. The metadata that can be collected through Bisq is simply the open offers on the network and the onion address associated with those offers.

Onion addresses can and should be reset periodically. The resetting of onion addresses doesn't change the account age either, since account ages are done on a per payment method basis.

If you choose to only take offers on Bisq and not leave maker offers on the platform then the amount of metadata shared across the Bisq network to all nodes is minimal. You could even reset your onion address after each trade.
