I believe there is no option for Bitcoin to fall dramatically.
First, Bitcoin is limited in supply, and the mining process is becoming increasingly difficult. As a result, it will be challenging to mine new coins.
In many countries, it is becoming easier to transact using Bitcoin, and the demand is rising rapidly every day.
If you are concerned about a potential dramatic drop in value, consider that in the future, it may become more difficult to acquire Bitcoin. Mining is expensive, and the number of available coins is limited.
In my opinion, there won't be any dramatic downturn, and future developments will undoubtedly be significant.
