The idea of Litecoin is to use it for daily transactions and small amount of money transfer, while Bitcoin is the save haven.
This will also solve the problem of the capped blocksize of Bitcoin when less transaction are done on the BTC Blockchain but on the Litecoin.
But you just use altcoin if you're sending it to the exchange site, and the important thing if everyone was thinking about the stability of the coin. in this time the price of litecoin is dropping for a lot and does it make sense to use litecoin rather than bitcoin for directly?
