I am not sure if you remember last year. It was about July 18. Bitcoin went down sharply. Everybody was shocked and made panic sells. 4-5 months After that decrease on the value, it went up sharply again. It is really normal to see this changes. You need to be very careful and patient. After that, you will earn ALOTOF money 
I dont think anyone from here or those who have even some knowledge about BTC will be doing panic sell. Panic selling is a concept for those who have invested to double their money and dont know the basics. We know that the price will rise again and never worry about the rate.
Pretty simple statistics if you really read those past happenings on bitcoins and this thing normally happens on bitcoins,But we can force anyone to hold since some of those people do it are afraid to lose more money from their wallets but surely they will regret as soon as BTC price will hit up again and Im so sure that BTC whales will do some extraordinary magic to lift this up.
