As expected, listening to too many markets at the same time generates LAG, I would observe a steady 96% in CPU usage when listening to 7 different markets simultaneously, and now it is alternating between 0% and 2% with only 3 markets (LINK)
I am so sorry if you happen to have been a victim, unfortunately the evil people of this world never sleep and we must stay alert, and if it sounds too good to be true, well it probably is. 😢
