It's going down because of the hard fork that is going to happen.
Therr will be double the amount of coins. Ao that at least halves the current price. And one, if not both of the chains will die out quickly and it will all be a giant mess in the ecosystem forcing people to move to safer and better coins. Dropping the value even lower.
That's how so many experts, including myself, are certain it will drop under $1000 soon.
The hard fork might actually be good for Bitcoin in the long run. It could put an end to the scaling debate, if one of the coins is wildly successful.
We can withstand the intermittent volatility.
