At the time of writing there is one DASH/GBP offer in Bisq (using Dash as base currency).
However it does not show on https://markets.bisq.network/?market=dash_gbp
Same for other Dash offers for other currencies. The markets.bisq.network shows no Dash offers at all.
Is the site broken?
I have similar issues with Bisq’s market/spread list. There are trades show which I can’t find if I open Buy/Sell lists for those currencies.
I forwarded this on the appropriate channel in Slack. Hopefully the operator will look into this and figure it out
