I paid 30 LTC for that
Yeah, but it's a well-known fact that no one gets ROI with Genesis Mining. They just pick whichever coins have the best profit at the time and hope that people will fall for it and assume that difficulty stays the same. It's basically a non-scam way of stealing your money.
Even if you did get ROI it would be such a tiny amount that you would have been better off putting your Litecoin elsewhere. It's unlikely for people to bid very much for this.
