Talking about cryptocurrencies, of course, it doesn't rule out investing or stocks, in this case, of course we have to be careful in investing because investing also contains risks. The risk here is to lose funds or other assets when the investment does not live up to expectations or even fails. Yes, it is true that we cannot invest and then only expect profits without understanding the risk of loss, but to warn of all possible losses, what steps should we take?
I think all types of risk are the same, the only difference is big and small. Investing without learning the basic concepts of investing, I think it's just a waste of money. However, the step that must be taken is to invest a small amount first, not immediately with a large amount.
Probably, those who start investing has already aware of their position and the consequences awaited them. As it involves money, either small or big investment it corresponds to risk. That is why we have to invest our money only the amount that we can afford to lose and we don't have to force ourselves if we are not prepared and most especially if we don't have any idea about the thing we invest in. In that case, it is to expect that losses are near to you, not profit.
