You are right probably that they do manipulate with orders and price limits.
When LTC price was very volatile, there were stuck orders due to inappropriate price limits of system.
10 July - 11 July night before settlement.
796 guys didn't cancel "stuck" large orders (several thousand LTC bids $4.5-5.5 when LTC price was $3.7-4).
As soon as they have changed price limits (without any notification) after several hours of waiting these bid orders were instantly (less than in 1 second) executed completely.
Only 796 admins could know exactly when to sell to these stuck orders. Why didn't they cancel them BEFORE changing limits?
People have lost a lot of money due to that, to say nothing of "socialized" or expropriated 73.97% of week profit of all their customers.
