It is all a giant multi-layers, quantum shift network

It managed queues, all of it.  From the hardware embedding of secret codes, queue management, make sure the diffussion of cards does not destabilize the block chain verification in the exchange network.  Automated queue management, from the autonomous bot at the factory.  All the trading bots are, ultimately queue managers, managing queues by quantizing prices, quantizing prices by operating with finite precision block chain.

Your person trading bot, same thing, it knows you because it knows your typical trading sequence. Yet again, another queue management problem.  You end up with a huge frigen, semi dtable graph as the trading sites aggregate, and generate coins on the virtual index of the aggregate.  The whole thing hinges on getting everything to market, ASAP, when the opportunity or necessity arise. It is semi stable on purpose, its the motion of secure digits that make prices.  But price is always uncertain, within a known bound.  The bots adjust, they get the uncertainty balance, but they still move digits.
