Same mechanism as BCH and BTG, if you've got access to the private key (and not in the exchanges)...
Sweep your wallet to a new wallet.dat immediately after the fork snapshot, then import the private key from the now empty wallet into LCC.
Once it's snapshotted, you don't need an active balance and there's zero risks of losing your LTC. Only downside is a very small transaction fee for sending your balance between wallets.
