Though a decrease is possible but $3000 seems way below the possible lowest limit for bitcoin. I believe bitcoin would never go below $5k for this century. Different might be the case after that. And it's higlhy likely for bitcoin to maintain a price between $10k-15k.
What can i say? Laws of the market are always valid. Demand for Bitcoins still exceeds the supply, so its price will stay at a relatively equal level.
