Getting error when starting bitcoind in regtest mode I tried starting bitcoind in regtest mode but got the following error.
Command :    bitcoind  -regtest  -daemon
Output :

Bitcoin server starting
Error: Invalid amount for -paytxfee=: '0.00' (must be at least 0.00001000 BTC/kB)
Since paytxfee is not passed as an argument you need to alter the value of paytxfee in your bitcoin.conf.
