If you follow RubyCoin news, you possible know RubyCoin was switched to the new blockchain and this coin is not minable now with POW.

As you can read at coin't BitCointalk thread, you had time before 20.11.2014 to withdraw your old coins to Bittrex. After this date old coins are useless.

Unfortunately, I don't get any warnings from developers or any user about this swap so our pool still mine with old wallet.

I write message to the RubyCoin developers about this, but not sure it can help swap not withdrawn coins. Looks like all RubyCoins not paid out until 20.11.2014 and mined after this date will be lost.
