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.
Yes I have the same thoughts as you. I firmly believe that BTC will never drop below $ 5k. If the BTC falls below that level, investors will buy them massively. As such, the amount of BTC demand increases and they continue to increase.
