Learned from my mistake in trading, i was loss alot of money because i did not use stop loss. So we should be use stop loss for every trade that we make, and use exchange that provide this feature. Crypto market is open all the times and we can not look in to the chart every times, so use stop loss and sell limit by the same times will make trading activity more profitable. I used exchange of Gate.io that has feature of trigger order so i can use it to setting stop loss and sell limit at the same times.
