a little warning to new users, especially if using JAM wallet on start9, umbrel, etc:

joinmarket works differently than Samurai and Wasabi. if you are a maker on transactions, you dont pay anything and can even get paid for providing liquidity. if you are a taker, you pay for the transaction.

Now, in JAM wallet there is a function to sweep funds. this sweep can involve being the taker on SEVERAL transactions that flow through your various accounts on the wallet. if you are inexperienced and use default setting...you could end up paying north of 50k sats per taker transacion. if the sweep involves 15 transactions, then you do the math you might be out 600k sats in fees for something you didnt really understand. so move slow with your usage of this privacy tool if you are new.
