The price of BTC cannot be less than $2,000!
If the price of BTC is too low, the miners will withdraw from mining and the market for cryptocurrencies will collapse!
And many whales will stop the BTC price drop!
If the price falls so low, miners will stop mining, then the difficulty will adjust so that it becomes profitable to again mine at $2000. All that being said, I don't see bitcoin falling to $2000, I think that the bottom has already been established and we won't see BTC falling below $5000 ever again, or at least till bitcoin is really finished.
