When bitcoin price down, people will split into 2 types, who panic and who keep calm and take other action to get profit. But for now, in fact is a lot of people who panic when bitcoin price down, and not change their investment to altcoins. We must face reality that for now there is rare altcoins that up when bitcoin price down because people already sold their bitcoins and safe their fiat. Maybe if a lot of people know how to minimize risk in trading, they will change strategy instead of only sell bitcoin and kept their fiat.
