well why not everyone will freakout regarding bitcoin price? the price gained a lot since last week and and it break another all time high this week. long term holders will ignore the price as long as it they have still a profit but for short term holders every hour counts they will freak out if the value loses 200 or 300 in one day.
You are right, only long-term investors can really make money, novice and short-term investors will face a little price fluctuations panic, their emotions is the ups and downs with the Bitcoin price, everyone must learn to manage their own mentality.
