I adore Streamate.
I have no idea what services you can provide with golds. The percentage is about 30%, and your payout can vary if guy tips you in pounds or canadian dollars, which make golds reasonable only for little shows in free chat or gold shows goals.
Not worth it!!! You don;t even get close to 50% which is complete bullshit!
Streamate gold is paid at a percentage. The cheques come when they say they will and have never bounced.
