ETC is $69 and it seems to pass $70 soon. The ATH of LTC was around $410 (May 2021). If LTC creates a new ATH, I think it should be above $500. However, I'm not really sure about the hype of LTC in this bullish season. If the demand can be quite high, it possible for the new ATH. But if there is no high demand on LTC, we may not see a new ATH on LTC in this bullrun season.
I predict, the highest price of LTC this year is around $300.
Sorry, but it seems that you are making a mistake here. The topic is about predicting the price of ETC, not LTC. The two coins, as you know, are different from each other.
You may have gotten confused because the names of the two coins are a little similar, so it is best to modify your post to suit the topic.
