I love finding forgotten Bitcoin on old wallets.
I just found 450k sats on my Bisq wallet.
I haven't used Bisq for almost 2 years. I tried to withdraw & it said the min fee amount is 10sats/vB.
I've just nervously updated the software & I'm waiting for it to finish synching. It looks like they've updated the min fee to 1 sat. I think the last time I used it was when the fees when sky high from the ordinals rubbish.
