So basicly if i set mintxfee to 2sat per byte i should be ok (it says 1 is enough now) right?
but the default value is 0.00001 (BTC/kB) if i look it up, am i missing something?
It depends on what you want. A 1 sat/b will get you confirmed anywhere between ~1-10 blocks. See
https://bitcoinfees.earn.com/ (Albeit this site can be very inaccurate, it usually gives a clear indication)
If you're in a hurry, it might be better to use a slightly higher fee.
Which fee should I use?
The fastest and cheapest transaction fee is currently 12 satoshis/byte, shown in green at the top.
For the median transaction size of 225 bytes, this results in a fee of 2,700 satoshis.
