* How to keep fees to minimum:
* Edit the joinmarket.cfg:
`$ sudo nano /home/joinmarket/.joinmarket/joinmarket.cfg`
* Look for: `tx_fees = 3` and change to `txfees = 1200` to pay 1.2 sats/byte (+/-20%) mining fee for transactions. Note that in times of high mempool usage it can take a long time to have transactions confirmed with this low fee.
* Set `#max_cj_fee_abs = x` to `max_cj_fee_abs = 100` to pay mac 100 sats per maker when coinjoining.
* Set `#max_cj_fee_rel = x` to `max_cj_fee_rel = 0.0001` to pay max 0.01% per maker for relative offers when coinjoining.
These settings might make it difficult to find counterparties to coinjoin with, see the [offerbook](https://joinmarket.me/ob) for the market and increase limit if offers are scarce or running into errors.
