ETH is much more popular and useful than ETC. But yes, you can invest a small part in it as a diversification strategy and hope for a bull run in future. But don't invest a big part of your income in it. It's just not worth it.
I agree. Even if ETC has its pros, I would still side with Ethereum in this head to head comparison because I see better potential in Ethereum plus the fact that Ethereum has the better value and marketability between the two. There are more projects that use Ethereum as well as their investment coin . People, on the other hand, also trust it more. In so many aspects, Ethereum trumps over ETC.
