I decided to change the power allocations to 25% to mining GH/s. This will allow me to slowly progress towards level 6 at which I will have 120% power available.
At my current GH/s rate a 25% allocations mines a little over 50 GH/s per day. The remaining 90% are allocated to mining back the Bitcoin I invested at 0.0016 per day. At the current price that is $2.03.
The withdrawal occurred within 5 minutes. Usually it takes between 5 minutes and 6 hours.
Be careful if you decide to invest in Metizer as there isn't much information about their operation out there. I've enjoyed the service so far and will most likely be mining Bitcoin and Litecoin once I've mined my initial investment back. Have a good one!
