Your comment about 8 years of experience in digital currency aroused my curiosity so I did a small bit of research as you suggested. What I learned is that you buy and sell WoW gold, among other in-game currencies and items. That says to me that you entered into an agreement with Blizzard and willingly violated the terms of that agreement in order to make a profit. There is even a warning on your website to your customers that using illegal gold may cause their account to be terminated so you can't deny that you know what you're doing is wrong. Now, that's far from the worst thing a person could do but it's probably not the best example to hold up when demonstrating your integrity.
While it is a violation of the terms of service the business itself of digital currency sales is a gray area market controlled by china. The warning on the website is required by google adwords if you wish to use any paid advertising. Everyone whos played an MMORPG understands the risk in buying gold or power leveling or even a second hand account. Before bitcoin ever existed popular games like runescape and its currency was used in a very similar fashion the way bitcoin is today.
I sold and traded the time a user invested in acquiring that digital currency or time spent creating his character, time is money is it not? Unfortunately I was heavily involved near the end of the prime of this business. You can look at Brock Pierce as a prime example who is also now heavily involved in bitcoin. For as much as you may think its not a good example, you'd be surprised at the amount of people that have done exactly this prior to bitcoins existance.
