We are long past the days of selling bitcoins in a panic, though the world has not yet adopted it, the relatively few adopters have come to trust the system.
people will stay panic selling. that will never change. just look at stocks, as soon as there is something that people consider to be bad news, they start panic selling like there is no tomorrow. just to prevent themselves from making losses. it allows smart traders to benefit from that situation and buy up at lower prices.
