CEO of the USA Investment bank, Lloyd Blankfein said "something that move 20 overnight do not feel like a currency. It is vehicles to perpetrate fraud" after this comment on Thursday bitcoin lose over 20% and I was panic to sell off my holding. But thank God the bitcoin has started recovering as we can see that it is currently above $9,700. I think this is another caculated attacked on bitcoin image in other to create FUD.
You shouldn't listen to any bank CEO when it's about bitcoin, I haven't heard a single one say something positive about it since the beginning (however, the blockchain algorithm is another story. It could mean that even financial people from nowaday think it may be reliable).
Plus, don't mistake correlation and causality. The drop may have happen because of another reason.
