I can't foresee anything like that,, below $4000 is not happening this year or even next year but that's just my observation.. This past corrections it holds only at $4100 and up and it was never down at that range.. It only means that even rumors and news against or related to cryptocurrency is not effective this days at all.. I think at this rate of observation it will make bitcoin stronger and maybe stabilize in the future..
Bitfinex has taken a dive below the $4000 mark for two times already after reaching an all time high of $4970 earlier this month. Bitstamp went down all the way to $4001.9 as lowest point.
Realistically speaking, there is nothing that prevents the markets to dive under the $4000 mark if large holders start dumping their coins, where the weak hands will follow after that ~ that's how it always goes here.
If the market remains stagnant and keep bouncing up and down between $4000-$4400, it won't take long before people lose their patience and start dumping ~ we shouldn't forget that a lot people are here for short term gains.
If things take too long, they lose confidence. Some people only bought themselves in this market because of the insane bull run to $5000, where they most likely assumed that it would continue to increase.
Let's give the market some time (a few months) to see what we are up to. At this point we still don't know how the potential hard fork in November, and then mainly the uncertainties, will affect this this market.
