Hello there!! I have a app in my phone that pays you LTC for viewing ads that plays as short videos. These ads displays are means through which developers of this app make their money, and they are willing to pay you for helping them generate traffic.
Payout is every Tuesday, if you get discouraged by the amount you get, you might not build up your LTC wallet for free.
WALLET
I will recommend Coinbase, using this wallet will enable you to receive any amount of LTC whether big or small.
