Investing in crypto-assets always involves significant risks. The price of crypto-assets can be volatile and there can be a substantial risk that the value of your investment may decrease, that you may receive a lower return than you expected or that you may lose your capital altogether. Each crypto-asset has specific characteristics, and you should independently conduct sufficient research and ensure that you understand the investment and the risks involved before making any investment decisions.
