LiteCoin Update
We hate to apologize yet again for the delay in implementing Litecoin, but the fact of the matter is that it depends on a variety of factors, including completing all of the above before we launch. We're looking forward to the rollout, but at this point are reluctant to speculate on when. We are sorry to keep Litecoin enthusiasts hanging.
