Buying gold online is not for everyone and it does have its risks. Powerleveling is far more dangerous and should only be done by a trusted company and even then there is chances that you account maybe banned. Blizzard keeps a close eye on the IP that you use and if you are highering a company to powerlevel a character for you you could be at risk of losing your account. Some companies may use proxy servers close to your location to try and reduce the chances of it being picked up on but if you do pay a company to do this for you understand the risks! The threat of losing an account by buying gold is usualy very remote but use a trusted company if you do to reduce your risks. I have listed several sites above that list good places to buy WOW gold or powerleveling.
