if there is a profit from ETH you have to share other coin benefits that you feel are good for tomorrow, I think LTC is not bad for making fences to be good and planting trees to bear fruit.
holding Ethereum at the highest possible price will be better, by looking at Ethereum's growth now I am more sure whether Ethereum will get more benefits.
Litecoin is good so it's not wrong if you have it, because it has a chance of profit.
if you benefit from Ethereum and you will buy Litecoin it might be a good thing, or you add more Ethereum is also a good thing, because the market is getting better.
