Useful how? And for who? Aren't most altcoins just something you use bitcoins to buy?
What does and can Litecoin do that bitcoin can't?
I heard about a coin called "Spots" that will soon allow you to exchange gold for coins that is new Like cash4gold for gold
I wasn't saying the LTC is more useful than BTC. It is the closest alt to getting it's own ATM. but it uses scrypt algorithm I was referring to the traits of the other sha-256 coins (NMC/PPC/Curecoin) because they aim to secure domains// be energy efficient// find cures for diseases.
How are they finding cures for diseases?
