"pools": [
        {
            "url": "multi.ghash.io:3333",
            "user": "copyfile",
            "pass": "x"
        }

should become:

"pools": [
        {
            "url": "http://eu.betarigs.com:3333",
            "user": "copyfile",
            "pass": "x"
        },
       
        {
            "url": "multi.ghash.io:3333",
            "user": "copyfile",
            "pass": "x"
        }

I thought Betarigs required the username to be for the specific rig you're renting? (usually it would be something like bruiser-4400 or whatever my ad number is)
