You could just keep the coins. Let them age for a while, like at least 1 year. You may be suprised at what they are worth then.
Good advice sir that's what I intend to do but I just wanna see if I can convert BTC or LTC to USD and then get them into my account ,otherwise I will always be skeptic about if it is possible for me or not.Before spending money to get good gfx card I want to be sure that these coins r worth it
