No matter how many times we have been through same scenario still the people will panic sell though they knew that the price will rise back but it's not that they don't have any strategy or they are in for short term profit and cannot be involved with Bitcoin for longer period of time. I have seen people saying stuffs like they are waiting for dip to buy but they don't and instead they end up selling their hodlings. I think one must know the basics of Bitcoin before deciding to invest into it.
