For those who had invested, i think it is normal to panic. Nobody wants to lose their hard earned money but for those who hold bitcoin from other means, i think they are more calm simply because they didnt really take out money as capitals. Some work in this forum and get paid in bitcoin, so, i think they care less if bitcoin remains stagnant at the moment or even it it drops below the expected amount, will not really hurt them.
Actually those people who have invested money in bitcoin and if the price is getting lower their investment is also losing value therefore they must get panic, but i will suggest them that their investment must have already lost a lot of its value, therefore if they will sell their bitcoin in current time they will even lose a chance of getting their value back, therefore i think they should hold their bitcoin for some more time and hope that they will get a good reward.
