I think one way to manage the risk is to know first what you are into.. Not just invest because people told you to do so and say it would give you profit right away.. Lets observe first.. Then the amount you invest well as many say invest only you can afford to lose.. Or dont put it in one basket only.. Invest on 2 or more crypto.. And The project or the coin itself choose the one that have big potential and have big market already,  or the one already listed on cmc.
