What are litecoins?

posted December 2013

WhatAreLitecoins.com is a new website that's looking to get litcoins to the public. The site looks really nice and it makes me want to do something about bitcoins. I think my next project will be a litecoin chart. I wish I had the qualifications to do a litecoin market but security wise and technically wise it seems really difficult at my level.

Well done! You've reached the end of my post. Now you can leave me a comment :)
