The fact that there is no perfect trading is enough to send out this very perception that it is not as easy as it looks like. Patience, greed and fear are the factors you need to tackle of course for the ill effects of these factors can possibly hinder your abilities to do the right thing in the very right time.
There is no perfect trading wherein you will not be able to have losses. Even those who are in the market for a long time and earning a lot from it lose from time to time but then they knew already what to do because they have experience it all before. It is about controlling your emotions and having a trading plan always because it is not only about how much you can gain from it but also about how you can minimize your losses when the market is against you.
Down market requires you to be patient and you can be one only after developing a winning mind set. IN the crypto market, all you should do is to refrain from selling low and investing wise. That is what I call a winning mind set.
Knowing when to buy and when to sell is one of the keys to being a successful trader. There are just times when you know when to act but then your emotions hinder you to do so and in the end, you become greedy when it is going up and become hopeful when it is going down which may not have a good result. Trading psychology is one of the pillars of trading and if you don't have what it takes then better just invest in it and wait for the bull market.
