$25 (5.73%) mining fee?

I’m looking to sell some bitcoin, as of this moment fees are listed at 102-110 stats/byte. my bisq wallet is the old non-segwit wallet I’m pretty sure but the trade wallet is bech32. why is this mining fee so high?

You can check out https://mempool.space/ to get an idea of the mempool size. The busy it is the higher the fees are. BTC was at all time highs so quite a lots of activity resulting in high mining fees. Hopefully it will settle down again soon.
