Many have asked 'is it possible to trade cryptocurrency comfortably and still make profit?' The answer could be yes, though it depends on many factors.
First, your success in cryptocurrency trading has a lot to do with your emotional state, because under anxiety you are bound to make huge loss instead of any profit so you need to first make sure your mind is stable and that whatever condition the market goes to does not affect you emotionally, because trading goes sideways at sometimes. Get your mind use to to the fact that there will always be fluctuations in prices and decide to sell only when you are at profit.
You can only trade comfortably with profit if you are confident with the coins you buy. Meaning, you are sure about the coins, don't just buy altcoins without doing any research, it is very important to know what their program and plan in the future. And always look the volume they have in the market and also the community traders they have it too.
