There is no specific date when the litecoin hit that price. But for sure this year and even this year that coin is possible to become thousand dollars each litecoin and I hope that is really happen to earn more money.
Yes that is right, It is not fixed to say anything about bitcoin or any other altcoin price in advance, we can only work on speculation but cannot predict as 100% correct. Litecoin is no doubt good for investment, because still it has still god potential to increase its price.
