Obviously I am missing something on this. How do you direct the transaction fee to a specific miner? I thought it just went out there for anyone to process. If you can, why don't people just direct all their transaction fees at their own mining operation or a friend they trust?

I think it goes to whoever gets the block it's in

This reminds me of a similar error from 2005[1] where a trader mistook the "price" and "quantity" fields of the trading software. Instead of selling 1 share for 610,000 yen, 610,000 shares were sold for 1 yen. The mistake cost around $225 million. [1] http://www.foxnews.com/story/2005/12/09/typing-error-causes-...

That reminds me of the time when, in 1989, I was playing trade wars, on a bbs out of San Jose; I was attempting to corner the market on wheat in the galaxy as I had pretty much all of it... I smoked pot and instead of buying all the available wheat, I sold all I had. Ruined my monopoly on wheat....

A famous trader known as BNF really capitalized on this incident. http://www.bloomberg.com/news/articles/2014-09-25/mystery-ma...

Well, if the entity issuing the TX was colluding with a miner, they'd craft the TX and the miner would add it to their mempool without announcing it to the rest of the network. Then when and if this miner finds a block, it would include this transaction.

Hand the signed transaction to that miner instead of broadcasting it to the network. It'll only get mined whenever that miner successfully mines a block.

Pretty bad article, but I couldn't find any better. Looks like a solid chunk of the money traces pretty cleanly back to tradeBTC.

I'd really like to find a good tool for exploring the graph of transactions. Most of the funding of the account that lost all the money have a similar pattern where a couple BTC is peeled off at each step and the majority goes forward in the chain till it all pools at 1QgTYzMYqStzZBQx8gguYaJQMjFRbagbh and gets spent. I wonder if thats just what TradeBTC transactions look like.

Instead of sending the transaction out on the p2p network for any miner to include, you just send it privately to the specific miner you want to mine it. Nobody else knows about it, so they can't include it in their blocks.

The problem (and the reason this really isn't a useful money-laundering method) is that people watch incoming transactions and blocks, and if a block is mined including a transaction that was not seen previously, it's a strong indication that there's collusion going on.

Usually transactions are published on the network and anyone can choose to include them. But a miner can add transactions that no other miner knows about. Usually you don't want to do it because it takes a long and random amount of time for the transaction to go through (you have to wait for that specific miner to win a block). But if you're mining it yourself or in collusion with a specific miner, that's a tradeoff you can make.
