The trading in crypto currency is every time risky even crypto is a risk. But if you loose, you get experience and this a the first step to start journey towards success. In my opinion, the main techniques to trade without loss or low loss include the consideration of following:
1. Market Bull or Bearish
2. Selection of trading pair/ coin
3. Grid/ chart view/ candle sticks
4. Market guess
5. Leverage selection
6. Continuous Market watch
7. Stop loss strategy
8. Study the techniques of traders
9. Trading not more than 30 mins means with intervals
10. Use trading bots
I know what you wrote here is good and if you look at it you will not fully get lost through this. but from your own way of understanding. I believe that even though you control all this things you most have a good of observing yourself. Because for trading you most lose and it's one of the elements. For traders to be more encouraged and smart of trade you most fail in so many times in trading. And after undergoing such you will still make a mistake one day for trading.
