Potentially, but Depending on how it takes off I can see it being the "Zune" of  smart contracts. It could entirely be very profitable, but unless something very fundamentally flawed with ETH, I don't think anything could overtake it... Not to say you won't make money (you probably will), but it is too new for me to invest... If you have thousands of dollars, then feel free to diversify but I feel it is more of a gamble right now.
