You can buy Litecoin at almost as many places as Ethereum and Bitcoin, since Litecoin is one of the long-standing Altcoins, and was one of the first coins to deploy the Scrypt Mining platform. While it is still under $4 per coin, there was a time when LTC traded above $14 USD, and is still one of the most reliable ways to send payments, and it is even faster than Bitcoin.
There are many miners still mining LTC, but because of tight markets, the price hasn’t fluctuated too much in the past few months, except for last week, when it bumped above $4 for a brief period.
One of the best places to buy LTC is Alcurex Exchange because of its smooth flow and free registration. However, here are a listing of other exchanges as well.
