Because of sudden dump liquidation of long became more so better strategy for future trading is keep laverage by 10x and use 5% to 8% of your amount not much and keep amount around 50$ to 70$ so you can manage risk of liquidation and later can add amount if your liquidation is near and enjoy small amount of profit like 5$ because in seconds market can move higher or lower without any expectations. Remember it will take so many of days or months to earn money but it will take only one second to make it nill. Be careful in future trade and manage your risk
