I have 2 questions about buying gold

Why buy gold though, when you could just buy NX and make the gold yourself?

This is how I do, My main never got banned so far and over 100k gold bought.

Create a lvl 10 char, which will receive the gold.
Have another character that has lvl 20+ to make it less obvious
and your main.

So transfer your money from the lvl 10 char to the lvl 20+ then to your main.

When Nexon scans for you account it should be okay. The worst thing that happened to me is that my lvl 10 char got banned, the rest is fine. Try it out.
Best website I use (since no one trade EU gold here) is vindictus.cc

they don't, and pcgamesupply.com

majority of the gold site are fake, but some are not. i have purchased from a few when i first started playing this game. if the gold your ordering is small than you'll likely get it in a few days, but if its over millions then expect long delays. 3 weeks or months. they will lie to you that they have a large stash somewhere just to get your order. i prefer only to purchase gold from trusted member on this forum.
