Trading more than 1b credits..

[Undercove]

I was looking over the trade forums and noticed a lot of auctions with items being sold for more than the personal credit cap.

How are they able to trade 1+ billion credits, outside of using same value items? Or is that the only way?

Using alts and trust. or GMI, where cap is 4b

Using a trusted 3rd party also works.
