That is how crypto world is. Prices change quickly, I as well lost some money I bought EBTC when its price was 0.3$ but no regret. And I believe this will go to the moon. If you cannot hold and you expect rapid profits investing is not for you, go spin a roulette. 
"go spin a roulette" lol, good one. Yes things chance quickly. bitcoin was on top of the world a few days ago at a whopping $7,700+ and right now at $5,800 and was at $5,600+ earlier today. Bitcoin cash is now at $1,500+ and continues to grow. How long that will last nobody knows but I agree with you "prices change quickly" indeed. Patience in the crypto world is key.
