Trading is definitely a challenging task. Greed, fear and risk all exist here. Those who do trading can understand these things. There is risk in every trade and it is with this risk that a trader has to manage the trading activities. If there is profit from trading, then taking that profit is definitely the right decision. There are many people who are greedy they don't want to withdraw their profit but they want to get more profit from a coin but then the price of that coin goes down further and at some point they have to lose. So whatever you do, if you get 20 to 30 percent profit on your investment, take that profit immediately. Although each person has a different strategy in trading, the objective of all is to make profit. When someone is in profit, if he can not withdraw the profit, that is his failure.
