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?
You said yourself that little can be done here.
The main and the first step is to invest only those funds that you are ready to lose without painful, everything else will be lost and will only bring disappointment in investing and the pain of loss. Invest free money without hoping for anything, it will bring you profit.
