It's just happened for some test running , i got my own wallet.
You mean when I find it out then they are able to help me out with that?
How exactly should I find the block for LTC?
Is this exactly what BTC-e said?
"May I know where is those generated amount of LTC in the network?"
If so, all you need to do is send them this link, the one you just gave me. It shows that the coins are freshly minted, and that all transactions into your btce account are in fact coinbase transactions.
