How can you not panic if BTC price in less then 4 days has decreased by 1000$!? Since everybody thought that previous price increase would turn out to be an uprising trend it turned out to be a reverse.
I'm not a true newbie here so I'm already a bit acquainted with such behavior but just imagine how rookies and newcomers could react to such fluctuations.
Panicking is just for people who did not have a good knowledge about the market's volatility, changing of prices drastically is nature of the market so you should always expect this situations if you want to invest on cryptocurrency.
