Since I know cryptocurrency my biggest fear is to lost all my capital or large amounts in trading or investment, because of the fear in me I don't do things that I'm not sure of or things I don't know. My fear to lose have always been a motivation or a reason for me to know things concerning cryptocurrency, I fear to start trading when I'm of myself that I know nothing to trade , fear to start investment when I know that I don't have a source of income.
Don't trade and don't invest when you're unsure. But here's the catch, you can set aside trading and not learn about it but you need to learn how to take risk in investing. That's the way to go in order for you to gain on this market. If you're not going to learn how to invest and take risk, you'll gain nothing.
My fear have been a motivation to learn, even If I start trading I may lose but not to lose everything because of the understanding I have. My fear to lose have always made me to take the right decisions and not to make money money my first ultimate in trading and investment but understanding as my first priority.
I know some of my mates who are into cryptocurrency that phobia to lose but even with the fear to lose they still go ahead to trade. If beginners allows their fear to motivate them to learn first their won't be drastic lose in trading.
Overcome your fear, that's what you need to do. Because with fear, it sets the mood to yourself not to try something new or what you really want to do which is to trade and/or to invest. When you always think first of fear, you'll not progress believe me. Just forget about your fear and keep on doing things with thought that you'll learn a valuable lesson whether you achieve success or not.
