Even the $1000 price level is nothing more than a great fantasy right now. Let's see if we can break through $500 and then $600 first. That alone will already be a more than heavy challenge with all the sell orders that will pop up as soon as we come near $500 and higher. It's not as easy as it might look to some people.
What if someone create panic near halving to cause dumping?
We could see 300$ in no time, just because nobody believe this could happen.
Well, it depends on what the price is by then. If it's the same as now, then yes, $300 can be reached easily with enough panic among traders.
