* Described in: https://github.com/JoinMarket-Org/joinmarket-clientserver/blob/master/docs/USAGE.md#try-out-a-coinjoin-using-sendpaymentpy
* 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 max 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 relative offer 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.
* press CTRL + o, ENTER to save and CTRL + X to exit.
* Can also [use the JoinMarket-QT GUI](https://github.com/openoms/bitcoin-tutorials/tree/master/joinmarket#joinmarketqt-gui-on-the-desktop) to send payments.
### Fee settings
* Edit the joinmarket.cfg:
`$ sudo nano /home/joinmarket/.joinmarket/joinmarket.cfg`
* Miner fee:
Look for: `tx_fees = 3` and change to `txfees = 3000` to pay 3 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.
Alternatively use `tx_fee = 10` to aim confirmation within 10 blocks.
* Maker (coinjoin) fees:
* Set `#max_cj_fee_abs = x` to `max_cj_fee_abs = 2000` to pay max 2000 sats per maker when coinjoining (more restrictive for higher amounts)
* Set `#max_cj_fee_rel = x` to `max_cj_fee_rel = 0.001` to pay max 0.1% per relative offer 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 the limits if the offers are scarce or running into errors.
* press CTRL + o, ENTER to save and CTRL + x to exit.
### Coin control
* List all UTXO-s in the WALLET with:
`(jmvenv)$ python wallet-tool.py WALLET.jmdat`
