Why do you always advice someone not to panic when the market is going down? They should cut their losses while they can.
it's always start with slow gradual drops and small numbers of "panickers"people get uneasy, followed by 30%-50% of btc owners are panicking, the dip will be even deeper
then more are infected by this "panic selling" up to 70%-80% owners, probably crash the market
which left the 20% as hodlers and/or buyers, who may become the next millionaires when market recovers
that's why noone should panic... triggered by small drops, panic, deeper dips, more panic, and finally crash
or if you really want to panic sell... as figmentofmyass said do it early
