your main fear is losing your money. To avoid this kind of fear, you need to invest the amount that you do not mind losing.
Investing money in good coins and to make more money with the invested capital sounds very sweet but that is not that easy. We need to act practically as well. The power or courage of taking initiative is very important and without it, you might never be able to start at all. This is the reason why one must observe the market thoroughly because it shows how much one could earn at an extended period of time. The lust to make money pushes you in to the market to start actually.
