Just remember to freak the fuck out and PANIC!

And on a serious note keep an eye out for big buywalls that pop in and out as those are better signs of coming dumps than sellwalls, sellwalls are used to keep prices down, buywalls to push them up. On the last dump there was a 200 ltc wall on 36 which was removed before the dump.
Of course whales are not stupid and probably are adapting strategys as i write this.
Not totally true. Yesterday on the second dump there was a 700/800 ltc sell wall on 110 or 100. They keep adapting. I hope their coins are finnished soon
