Sometimes FUD could decrease the price if a mass media could misinform people who holds bitcoin anything bad about it even it is not true. It is only sometimes since many people are still buying it without those and it just give opportunity for other people to buy bitcoin in low price and after some bad events cause by FUD, the bitcoin will still rise and those who buy low have a profit and those who is in part of FUD just lost the profit. Bad for those shitheads, good for them that they did not get something from bitcoin because of their lack of trust on it.
