For me, the most critical situation is when those crypto whale sell all their asset at once. It feels like throwing crypto with a useless value after they trade it on a real money. They have a good profit but after that the value of those specific coins suffer a lot and can decrease it value for almost 75 percent. Like what happen in early first quarter of this year 2018, it feels like the crypto is sucks and many of us experienced loss and failed at once. Just my own opinion
