Zec breaks through a strong support area, this indicates that zec will rebound at a price of 500+, remember!!! the crypto market is very volatile. Whatever it is, a large margin is key to prevent your position from being liquidated because the battles in the market are very fierce. My advice: use a margin of 3-6% maximum of your total margin to maintain your mentality and avoid overtrading, and it's important to use isolated margin if you want to be safe.
