CC domains don't sell well and mostly must be short (4-5 letters), and only go for max XXX on avg. But yours can be used for crypto website. As others have said, you have to be patient. Problem is that it's a bit long for the TLD and is a lesser-used synonym for "buy". I don't think you'll get more than $500 realistically and it could take a while.
I love .CC for many reasons, mainly ease of typing & memorability, but unfortunately the market does not agree.
