Litecoin can be efficiently mined with consumer-grade hardware. The Litecoin blockchain is capable of handling higher transaction volume than its counterpart - Bitcoin. The Litecoin network is scheduled to produce 84 million currency units, which is 4 times as many currency units as Bitcoin.
One of the aims of Litecoin was to provide a mining algorithm that could run at the same time, on the same hardware used to mine bitcoins. With the rise of specialized ASICs for Bitcoin, Litecoin continues to satisfy these goals.
Scammers find it much harder to double-spend Litecoins because of the fast confirmations. Double-spending of Bitcoins on the other hand is not that rare.
With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.
