This is what some thought about Dash when it was at 70$ and thought I'll buy when it drops back to 10-15$ and those guys are still waiting  
What you have to note is that yes, some correction will take place and LTC may go back too 200$ but it won't go back to 100$ in my very personal opinion  
There is coins that are not altcoins . They have theirs own systems ecosystem and infrastructure already set to grow and LTC is one of them. But even that does not matter. Rise and you will rise , fall and you will fall. This is what some kings can do my friend and if some decide that LTC or anyother coin is the next BTC , it will happen. No one can stop them.
