Srsly, this isnt threat "how much gold do you have guyz?!?!??!11"
As someone said 0g will be enough
Also you DO NOT feed your family with in game gold, just spend it peacefully if u want to buy something that wont be obtainable in cata etc. dunno what else to say
I understand the thing "i dont wanna go bellow this" but on what are you planing to spend it than? At least go buy spectral tiger for 250kg and there you go =)
