Apart from Bitcoins which has proven to be consistent in price appreciation, which of these two coins, ETH and LTC you think is most valuable.
I'll put my trust on ETH since its been my second choice after Bitcoin. ETH's price has been improving in the past few days and its been widely use by some ICOs so I can't think of any other altcoin that could replace BTC in the future aside from ETH so for me it is more valuable than LTC.
