At worst it may fall to 400 dollar.
400 dollar is an impossible worst case scenario in my opinion which can never happen again, remember the resistance there was for the price to go below it. that resistance is now at $600 and even if it is broken, just like before it will jump back up in a short while.
Yeah, some are just manipulating the dumping of the price of bitcoin, But it can never go below $500 or so. Maybe in a couple of weeks or months. We can feel the pump of the price of bitcoin so that all of us holders will be benefited. I hope soon it will reach its peak. In trading, I am not that knowledgeable when it comes to resistance etc.. But I have a basic knowledge when it comes to the principle of trading. Cheers !
