You can do one thing when running bitcoin-cli paytxfee 0.1 command, you can run command to update value of paytxfee inside bitcoind.conf file.

like this:

bitcoin-cli paytxfee NEW_AMOUNT && sed -i 's/paytxfee=OLD_AMOUNT/paytxfee=NEW_AMOUNT/g' ~/.bitcoin/bitcoin.conf 

This will set fee for current session also when you restart bitcoin core price will not alter.


You can make it persistent by adding a line paytxfee=0.1 to your bitcoin.conf file.

You cannot make bitcoind persist the result of the paytxfee RPC.
