With the experience that you have in trading especially with 5 years, you might have learned allot already, but that doesn't guarantee you a good profit as markets are still unpredictable sometimes. We are doing the same thing, I am also trading with leverage and I find it better when my leverage is x20 or higher, this way, I can maximize the profit but also increase the risk of my funds losing if the market didn't adhere in my position. You might need to use stop loss and stop limit in order to decrease your potential losses but I will still advice that you join some cryptocurrency trading signals. The advantage of that is that it will lessen your time when doing a fundamental and technical analysis as it is like a collaborative platform where you can get hints of which coin will be good at a time.
