Some people are unhappy and they're rightly so. But let's take the example of litecoin and ask for your opinion.
This is the 'All Time Chart' for litecoin, from Apr 28, 2013 to Jun 14, 2018:

People who bought litecoins on Nov 28, 2013 (date is red underlined), when the price was $50.27, after 3 years of long waiting, they should have been very unhappy, right? Would they have had to sell their coins on Dec 11, 2016, when the price was $3.69?
Big question, huh?
Litecoin is a very good example for us. The lesson is this: You never know when the price will blow, so be patient! Patience is the key to the success.
