In the world of finance, the investments we make, are often also full of risks. The risk's a normal thing for every commodity which we invest meaning this's not only on cryptocurrency but also can happen in a number of other investments, namely: stocks, mutual funds or the like. Risk can cause the investor's principal value to decrease.
Central bank Governor of Spain has told the cryptos bring more risk than the benefits to get. but I believe on more risk more gain theory. If you can not trust crypto, you will not be able to see its value. Risk is associated with all kinda business. It just has to be calculated properly that which one would be profitable for you.
All of that depends on each of us in responding to it and managing it, if we understand the performance and the risks I think there will be many benefits rather than the risks.
