I just started messing with LTC and i was wondering if someone could tell me a good online wallet?
i am curious to know, shouldn't you be running a full node when mining?! and that can already be used as a wallet.
also if you want a wallet, never use an online (web) wallet no matter how safe it is. always use cold storage.
besides as long as you can run a full node it is the best option, if not you can go with an SPV client. litecoin has an electrum version clled electrum-ltc which you can find on litecoin.org website. it is your second best option.
