Hi Guys…
i downloaded the app for win 64bit
and Downloaded some blocks.
encrypted and unlocked for staking
but i dont know how to stake please help me in full way 
you cannot “stake” litecoins…sorry but litecoin is a mineable only coin…
but …
the miner’s name was LiteCoin Core
it downloads some thing and then nothing…
how it mines??
you have to use your cpu, gpu or buy an asic miner and point it at your wallet or a pool to mine coins…
please read this guide:
litecoinpool.org/beginners-guide
litecoin core is not the name of a miner…it is the name of a wallet
I believe you can’t stake LiteCoins. Whatever you have downloaded, I think it has no use. I’m sorry.
