You know any investment is a risk, but you can carefully choose which investment will be safer. I recommend you to invest in projects which relates to the real sector of economy such as CryptoRiyal.
I totally agree. One way of reducing risk is to know exactly the purpose of the project you are investing in. Make sure there is always some real life applications and the project is doable.
Considering any kind of investment it was all very volatile. So only put the money that you can afford to lose.
