My condolences to the All people who lost everything in this dump. This is how the Market moves. People are greedy now a day.
They want to be rich overnight so they use high leverage in their trade. when this type of dump they see. they will cry like a baby.
Market have simple rule, one lost and other one win.
If you don't want to lose money then do trade with all of your senses. Don't be greedy and don't be impatient.
