Sometimes many people try to manipulate the market and buy precious tokens cheap and selling high later.They intentionally cause fear and panic in the inexperienced members and take advantage to perpetrate their greed activities.
In my own opinion, that is called strategy, you should always take advantage of the market price while it was dumping in order to earn more profit in the future.
Part of the game where everyone should understand and realized, this type of strategy is for those who really have broad knowledge about the business, most of the time this attitude also bring more success as you can wait till you see that the value turned to your desire amount.
