It is so impossible to trade without any single loss. But the thing is we can compensate every loss thru average down. So do not trade the whole money 100%. Always trade in portion. One more thing do not trade using margin if you dont know how to manage it.
Yes, I agree with this, Based on my experience and at my current knowledge about trading, I don't spend all of my profit 100% at 1 coin, I select a lot, observing the status of the coins I bought. sometimes it's a loss, but it's ok, I guess it's a part of learning, since I am still a newbie.
