It is definitely very negative for bitcoin market as it gives a perception to masses that they need to withdraw their investment and save their own skin and that the world is moving forward and thinking of anything apart from bitcoin to invest it.
It is bad for sure because if some people will say bad or joke about bitcoin then it will affect the price of bitcoin, but I think they are saying and joking because they are lack of knowledge about bitcoin, but even in this kind of circumstances bitcoins is getting high day by day, no one can decrease the price of bitcoin even if it be hated by almost everyone, those who know bitcoin is profit worthy let them say what they want you just trust bitcoin and keep in going with profit.
