Trying to guess which will be next is a fool's errand.
Well I guess the good thing is that even a fool can make money. So far I have done alright and if anything just sold 2 of my coins too early. Its true that you cant lose selling at profit

Though the two are soon parted. Good luck to you, but for every pump there is another coin like ARCHcoin that gets dumped to the ground. How do you avoid that?
