No matter what you are thought, you must know this that to be a successful trader, it takes practice and consistency.
New traders are tend to invest in coins where their friends invested and earned a huge profit. Mainly, in recent days, in last quarter, we could see too many investors into trading based on word of mouth spread about crypto currencies yielding good enough profit. Mainly new traders put their money on a coin when that is on its uptrend which is not appreciated. They would always fall into loss and when they see it, they just close off the trade in loss and come out as they are not used to it. Patience is the key to success in every field. Analyse the market and place your orders based on the updates on the coin one is invested.
