Actually in reality most of people who fear to lose will not learn because they're scared to take a risk. When you're fear to lose your money, you will be very careful and you wouldn't leave your comfort zone. Just like someone who's start a business, there's no business will always make money constantly everyday.
Fear related to bitcoin trading or cryptocurrencies? I don't think the person is interested in learning anything because if he were, he wouldn't think to visit this forum after learning about cryptocurrencies. Mate, anything related to bitcoin or other cryptocurrency-related activities should be done with caution because there is always a risk involved, even when trading bitcoin. If you don't think carefully about it, I don't think you can succeed. You see, there are times when you have to stop and ask yourself questions before acting, because cryptocurrency is not what you think it is, mate. You will encounter challenges in every business that will also force you to go to a lender and still lose some money on the venture.
Even though I am aware that losing a significant amount of money in cryptocurrency is an extremely painful experience that no one likes to deal with, the fact remains that you cannot engage in cryptocurrency activity and expect to always make a profit. This is something that new members of the forum should be aware of before committing to any cryptocurrency-related activity; if you cannot bear to lose even a small amount of money, you are not capable of trading or even purchasing bitcoin to hold for a while I don't think you can do anything concerning crypto activities.
