When I first discovered crypto. BTC, LTC, DASH, stood out as practical coins.
I don't hear much about LTC nowadays.
Still alive and doing well as far as I know. They might not be as famous as other coins, but they are still here and being the guinea pig for bitcoin. Which means that before being implemented to bitcoin, Litecoin will do it first, like the block halving.
Is there a preffered LTC wallet?
There's a lot who already answer it.
Are people using it much?
Yes, as investment, store of money or simply money. Specially when fees in BTC and ETH are high, traders or gamblers switch to Livecoin.
