One of the reasons why traders loose money everyday in their trading is 'greed'. A trader will hear about a particular coins he wouldn't even do research or proper findings to know the future of the coins which he wants to trade his money on but rather the greed in the trader will push him to use all he has with the aim of making 4 or 5 times of his trading capital.
Traders are big risk takers so everyone should know what he or she is trading on so that when you loose which is normal, you will learn more.
No trader is perfect but mastering coins you trade on can help you, remember trading is like a gamble you either gain or loose.
Do not trade with everything you have,your egg can not be save in one basket, I have lost but I have gained more in trading with the help of research and mentorship programs.
I agree with you- sometimes it has something to do more than just the research. The problem with most people is that, they tend to be greedy in meeting their desired numbers and reaching for a specific profit threshold before they cash out, resulting to a more loss on their end.
Trading is extremely risky especially if you are new to this field. The risks involve in substituting your coins with other cryptocurrencies is just way too high to the point that profit may be compared to as of a bank teller. It is nothing but essential that you must always cash out your investments even if you see just a tiny profit on your end. The more you wait, the more you subject yourself to greater risk of your profit turning into a loss.
