There are always risks, especially when it comes to cryptocurrencies. But risks can always be reduced and maximally secure yourself and your investments if you invest for example in different projects, in different directions in the crypto industry: investing in ICO, PoW/PoS mining, launching masternodes, trading on the stock exchange and much more. In the event that if you are unlucky in one of these investment options, then your losses are compensated by profit from another source, this is the most correct approach to investing, as I believe.
