OP is already underwater on ETH while the LTC price in terms of BTC is sitting on the low-low. Ain't hard to see where the upside is on these trades atm. On one hand, I feel bad for the newcomers that are gonna be slaughtered on ETH as this bubble deflates. OTOH, caveat emptor and take your profits when you get them in these altcoins and add to your BTC stash.
