I guess in the price of bitcoin right now this question cannot answer or this question is impossible to reach 1000$ now is impossible to reach because the price of bitcoin today is 2500$, maybe if all of the biggest traders in the world sell theyre bitcoins, we will not ever see the bitcoin in this price,
It looks like not get bitcoin but some other altcoins as well. There might be some doing it intentionally or other may have influence on the sudden dumping of all coins currently. I haven't see any negative news that will really cause this dumping. I can only speculate that people are selling because we have touched $3000 and its tough not to sell your bitcoin because the price is really good.
