I think you need to think about your investment. Do not believe in one or two facts about this coin. You can invest in more attractive coins like eth btc tron, i Think this coins have a big future and big potential ! Make only deliberate choice! Do not make stupid actions

I agree with you do not put eggs in one basket this will only make you regret in the future. because this is very risky for your financial if you invest your money in one place. there are still many more promising popular coins like eth, btc, and neo. it would be better if you divide your capital in some coins in this way the percentage of your profits in the future will be greater than putting everything on one coin only.
