I sincerely believe that anything can happen, but always taking into account the United States elections. Whether we like it or not, the US market is the determining voice of where the market will go. From time to time I like to read articles like the ones you link in your post, but I don't like to be influenced by what they say in those articles since in 99% of the cases they only serve to manipulate. As we have seen in recent weeks, Mt. Gox creditors have not sold (at least the vast majority of them) the Bitcoins they have received, something that many people feared and that some media and specialized sites "announced"
And yes, I think Bitcoin can fall below $50,000 and then regain value again, whoever wins the election, it's just that depending on who wins the election, that recovery in value could be faster or slower.
