very true, that greedy nature will bring destruction to the traders. in trading we need to get rid of the traits that make us do things without calculation. when we trade using emotion, greed, and too haste, we will tend to make mistakes and this has been proven and must be avoided.
right, sometimes we want to get big profits and continue to hold our coins even though they have experienced a fairly high increase and finally we get nothing because the coin goes back down and doesn't go up again.
that is what many people often experience because they are not quite satisfied with the results they have got.
I am agree, experience is best way to make profits. We should never attach with our coin or token. If we are holding bitcoin, its good long term investment but for some altcoin, its better find a right price to sell it and convert it to bitcoin
