How do you actually deal with it? Do you wait and keep on waiting in hope that it will bounce back up and return your investment or you sell and get whatever left of your investment?
First of all, doing your own personal research before investing your money won't make you run into a loss. But just in case the going turns bad I'd suggest you just just follow your heart at this moment because since a coin that's still just new too have crashed so badly, the chances of the price picking up are very low and as such your investment might end up going with it, so once you notice it's falling beyond the red line it's better you pull out so as not to cry at the end
