I am not entirely familiar with how LBC works. Is this a withdrawal transaction to your wallet, or is this some kind of internal transaction within LBC to credit your LBC account?

That depends on how you define "lose". If you are the one receiving the transaction, and not the one sending the transaction, then as time goes on, the possibility that one of the inputs gets double spent increases. Pretty much every other definition of "lose" would result in that you cannot lose the coins.
