How low would Bitcoin have to fall before it was no longer recoverable?
It would be very impossible if the price of Bitcoin would decrease to 1$, even though its reach in the next ten years, I think this will be very unlikely to happen, because the quality contained in Bitcoin is what makes Bitcoin itself so valuable.
Bitcoin is very decentralized, and this is why it will always survive and will not make it disappear and will remain as long as Cryptocurrencies exist.
With some understanding above, I believe that Bitcoin will recover and soar to a higher price, sooner or later according to knowledge and research in the Crypto market I think this will happen.
