ETH in Bisq?

I have an ETH Address set up in Bisq. If I send ETH to it, can I use the ETH for security deposits for BTC transactions in Bisq? Or can I swap it in Bisq? Is there anything else I can do with ETH in Bisq? TY.

The purpose of filling in your ETH address in Bisq, is so that if you sell BTC to buy ETH, the buyer will know where to send his ETH to.
Bisq only accepts BTC as collateral, this could change in Bisq2 when it is released and when additional modules to trade directly with alcoins will be available
