FINALLY someone has come up for a use for LTC. Use it as a testnet for real currencies. That's all it's useful for.

It was when Bitcoin had the DB issue that caused a temporary fork that I came to the conclusion it is good that we have Litecoin (something extremely similar but different enough to perhaps be safe from such a problem if such an incident occurs again).

Putting "all your eggs in one basket" has never been a very good idea (which is why NASA has redundant systems in case of failure - in space you don't get a second chance).
