Certainly! Should this deter you from such investments? I do not think so. The fact is that there are always risks, just as there is always potential. But think about this:
If you avoid the risks of crypto currency, what risks do you choose? In what will your money be? Maybe you do not make savings at all and immediately put everything on a beautiful life one day ... Even then your financial risks will not go away anywhere - moreover, you only increase the chance to stay at the broken trough. Unfortunately now people are more accustomed to making debts than investments, so many of those who seem rich lives actually are poorer than the last vagabond - at least there is no debt. It is necessary to make savings and it is necessary to do them wisely.
