Selling 5-10K + BTC? Why not to sell them on a public exchange...

[StarfishPrime]

It makes no sense at all. Are these stolen coins being dumped or is it just ignorant trading?

As of the past few weeks, there are plenty of places to sell that kind of coin with little or no price penalty. Tradehill, Coinlab, etc etc etc all looking for off-book or dark pool trading for big clients.

There are lots of big orders out there, it's just not too wise to assume they're all on Mt Gox!

80% of published btc trading != 80% of btc trading.
