...and why do you think so ?
We have already passed this amount and we are now waiting for the halving and what the price is going to be after the halving.
It could be possible that the price could drop back to $500 but I do not think that that is going to happen.
We are already in around $600+/btc and we have even reached the $700+ mark. Who knows, maybe it will go back to $500.. But with the current trend, it will not happen most likely... Bitcoin price will surely go up and if predictions were ac curate, it could reach the $1000/btc that everyone is wishing for..

We are currently at $670, way past the 500 mark. Chances are the price will swing from about 650-700 this week. Very unlikely to drop to $500.
