We can expect ATH for almost every other coin in the market considering this years dramatic falls, some good updates and countries going full positive about their acceptance. LTC stands amongst the top 5 coins so if there is going to be up surge then people will have most of the attention to this coin along with others too. Last year many people got lucky and hit the jackpot who bought the LTC as low as 30 bucks each. It was like same situation where you bought the BTC at couple of 100's and then it spiked all the way upto 19K USD. Possibility of LTC going up is huge and yes I would invest into it if I were you.
