I have more Ethereum than Lightcoin but I think it's sensible to have some of both. Ethereum could be a threat to Bitcoin and Litecoin can use all that's good with Bitcoin and be more experimental.

2018 is going to be interesting. The fall in the overall market cap so far this year is alarming but it still feels like cryptocurrency is in its early days. I'm not investing money I can't afford to lose and I can keep my coins in these downturns. Hopefully things will look better by the end of the year.
