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.
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.
You shouldn't be afraid of anything. If you continue to be afraid that you will lose your money, I don't think that is a good idea for you to make. I will also advise any beginner not to be afraid when planning to invest, but to just inform them the risks involved and how to make a profit. We can't start investing and think we can make a profit quickly; that may take time and patient. You won't lose anything, mate. If you invest in bitcoin, your money will be safe as long as you keep your address private. Since you also know about cryptocurrency already, you won't be able to lose anything. Your fears, in my opinion, are only delaying you; they are not motivating you. Sometimes in order to succeed in this world, we have to let go of our fears and take some risks.
But since you stated that you don't have a source of income, I automatically assume that now that you have started earning, you have put your fear of investing aside to begin trading. In my opinion, you should start investing if you have other ways of supporting your daily needs; if you truly mean to, don't be afraid, the future is very important. You said some of your friends are into cryptocurrencies; don't they succeed with it? If they did; in my opinion, their successes will inspire you more than any fear at all. If they did not lose you can start as soon as possible.
