In wallet options section it shows these two settings
-paytxfee=<amt> Fee (in BTC/kB) to add to transactions you send (default: 0.00)
-maxtxfee=<amt> Maximum total fees to use in a single wallet transaction, setting too low may abort large transactions (default: 0.10)
If I set these two settings in the bitcoin.conf which one will override the other ? or how does in work ?
