I found out that you can mine Litecoins which can be then sold for $.
What I do is I run the Litecoin application and a GPU miner called CGminer (for Litecoins) which uses Scrypt as the algorithm.
Just thought people might be interested in utilizing their GPUs to make extra coin/profit while they are idle and not being used.
Anyways this is my second post here. Glad to be a part of this community!
