Backing by what?

I have heard that if you find bitcoin fork then you have to be carefull because sometime that is the scam coin.

As for litecoin, I really like this coin for a long time. I still my investment since 2017 ago and I got profit.

Litecoin is bitcoin mini, some feature in litecoin most likely same with bitcoin, this is why there are so many people who will talk that litecoin is like bitcoin.
