Why fall to the bottom if adoption will be increasing in the near future? For me zero value of Bitcoin will be far more impossible unless Bitcoin will be banned totally by governments all over the world but that is impossible to happen as Bitcoin is decentralized and it can still be used by holders, enthusiasts and investors even when there is a strong implementation of ban in a specific country so value might fall due to volatility but not going to like zero value.
The fact is it's true that Bitcoin must have a price.
I think the decline this time was due to economic fluctuations, currently the stock market and crypto market are experiencing severe shocks. so it's natural when many bitcoin users sell to reduce the risk of loss. maybe when the market looks good, the increase will be greater than last year's ATH.
