one thing, learning to trade cannot be compared to learning guitar,
learning guitar needs to practice directly,
but trading, we need theory and practice, but we don't have to feel defeat, because we can analyze the movement of coins without having to trade, and after the results of our analysis are good and accurate, then we can start trading.
Well, same thing about playing guitar. You can practice until you are perfect in your room but you think you are perfect without getting outside opinion.
Play in the real world. Let real people listen. Then you find out how good you are in public. How good people think you are because that is all that matters when it comes to music.
Any industry you only know how good you are in the real environment. Trading in practice without emotions, without real money at stake and real market conditions?
