I recently updated Bitcoin-Core to 0.18.0 and then it had to resync the blocks which has taken 8 days so far and is only on 67% completed (using windows 7). I have the files saved in D:/.. I noticed the config file was blank. What should be written in there in a standard case?
I did try to install node launcher but was to technical for me, but after I tried this I noticed I had another bitcoin folder in F:/ which I have since deleted.
