I don't see how stopping staking will affect bitcoin!!!!
First, Bitcoin has nothing to do with Proof of Stake and it has nothing to do with Altcoin, so I don't see how it is affected by this ban.
Secondly, even if these rumors are true, they are still only fears, and then they are only in the United States, and companies that wish to pursue staking can operate in any country other than the United States that does not prohibit staking.
In the end, I see no reason for Bitcoin to fall as a result of this news.
It should not have an effect on bitcoin but retail investors do not care, they see more regulation and immediately assume all the market is going to be affected, which then turns into a reality as they sell their coins and then this strengthens the idea that this is the case, this explains why bitcoin is going down again, but smart investors will immediately realize the mistake those people are committing and take advantage of the cheap price at which bitcoin is trading right now.
