Although I am biased, I like Ethereum. The amount of businesses interested in it along with the amount of developers supporting it gives me confidence in the project. There are still several vulnerable areas that offer risk, but I think it is less conflicted and more sound than other coins.

Don't get me wrong though there are plenty of good coins to invest in besides Ethereum, but at the end of the day most of this conversation doesn't even matter because of the correlation in price between cryptocurrencies currently.
