I think it's better to spend more time and invest in solid project. I usually dump bad coins early to minimize risk and sometimes the price gets really high 
I really don't understand why some shitcoins are so hyped/expensive...
Easy profit. Take TRON for example(not saying it's shit) a coin goes 100x within a week, for some reason that I'm still not sure, don't you think people are going to get hyped about it. Who won't like the idea of making your money 100 times. I really don't understand why some shitcoins are so hyped/expensive...
