There is always a risk in investing,now everyone knows how risky to invest in cryptocurrency,you need to have a lot of experience in trading.
I think the only risk, or rather stupidity that can allow a beginner, is to start buying coins at the time of growth, and then get a wild minus, as it was the top. So it is not necessary to invest all in one token and wait for the profits. Read, learn, you it will take not more than a month, but then the results will be, but not a good call.
