These motherfuckers are acting smart.
I just watched in progress what's happening on cryptsy.
1) The bot is detecting the lowest selling current price.
2) It is trying to manipulate by putting the price even lower - just for 10-15 seconds. If no one is selling even lower, it takes the order away.
3) Then it waits for 5-7 seconds, and tries dumping again - trying to provoke someone watching it to sell even cheaper than itself. As soon as it happens - it puts the lowest price again, and repeats the algo. Basing upon people who hesitate and panic, it gradually dumps the price.
LUL.
