This trading strategy in crypto sounds easy, but it's not that simple. Selling coins can be done when prices are high, that's an opportunity we can take to get a profit. And no one can really predict the bull market in the crypto market.
It is really not that simple because as long as you hit the chart, you will have to start making some concrete and fast decisions. The problem though is that a lot of traders want to have it all. When the market gets above the breaking point, they still want to hold on to it, and trying to see if the bulls will keep pushing it higher, and for a volatile market, we are all so conversant with how the market can drop pretty fast. What is important is not to get greedy, have a plan on how you want to be selling before even entering the market, and stick with a very good stop loss.
