Great to see you alive and well Bradley, and yes there is a few market maker bots trading CTP, they are taking profit by trading the spread, buying low and selling high and then repeat automatically, not much to say about that but it makes it a bit harder to sell with limit orders rather than market orders, though market orders could crash the price quite fast with the amounts I assume that you need, but don't worry I have set a limit order to buy 100k CTP for 10 Hive ;)
