My question is who fucking spread fake news here?
you are!!!
BlackRock never denied anything because they never said they are doing something they weren't. you are just making things up in your head. all they said was that they are looking into cryptocurrencies as viable investment options, that was all. and the price rise wasn't that significant either. this is nothing new, it is not like we went to $9k+! this was a small 10% rise above $7k resistance which was about to happen with or without BlackRock,...
I guess people were just expecting something that will dramatically alter the tide of the market. so they misrepresented the facts in the statement made by BlockRock. BlockRock handles several trillions of dollars, people will want them to throw some cash to crypo.
