You don't get 10x what you have in wallet, but:
 You get 10x what you have in your address.

Wallet=many addresses.

LCC comes from what you got in your LTC address x10.

If you got no idea what amount of LTC you got in what address, - you can see it using Litecoin core wallet. To see what address has what amount click:
Preferences - options - wallet - enable control coins function (mark it and click ok)
Send - inputs ( after clicking inputs you can see how many coins you got in which address)

You seriously should KNOW this, or else you might lose your LTC if your PC with LTC wallet ever crashes.

You OWN only those LTC for which you know private key, if you don't know private key you don't own it.


If you try using more than 1 PC with LTC core wallet you might end up losing your LTC as well.
Also you might end up losing your LTC at the very moment you click transfer LTC and your PC crashes (new LTC address for change doesn't get saved into wallet - and you lost access to your LTC)


For example:
- you have 1k LTC in address A
- you send 1 ltc to friend
- 1 LTC goes to his address, and 999 LTC goes to your NEW address.
If your PC crashes at the moment you send LTC you just lost 999LTC.

If your LTC was bought in parts for example you bought 300LTC than 700LTC, than your change will be 300-1=299LTC and you just lost 299LTC, or 700-1-699 and you lost 699LTC.
To prevent NEW address creation while you transfer LTC you should put your LTC address into field Non-standard address change and check it, option is in Function of coins control.
