Hell yeah! I doubled my money in four days haha of course there's gonna be pump&dumps like these in the beginning, but it doesn't matter - the Ethereum network is the future, so even if you buy now, in a couple of years the price will be over $50 or even over $100 so you'll get major returns nonetheless. But, personally, I'd say you missed this pump, wait until it's dumped again and buy in, then HOOOOOLD 
Doubling money is easy when you consider the successfull one. But did you already lost all your money by betting on the wrong alt? :p
Cause I did once
The key is to choose the winner of the crypto currency. It is very difficult. Most people lose in the altcoin.
