The decoupling of bitcoin from the stock market is usually an exception. If you take NASDAQ and bitcoin charts, you will see that they usually move in the same direction. They have some differences overall, but they are both an assets so the same rules apply for both of them like if the economy is getting worse, there are less people that will buy bitcoin and stocks.
There is a bigger difference that you ignore. The stock market is more dependent on supply and demand, while the cryptocurrency market is not entirely based on supply and demand and is manipulated most of the time. Both are financial markets and part of the economy, so macro news will still affect them. There is still a correlation between the 2 markets, but they don't quite move the same all the time. In the first quarter of this year, the stock market didn't have any significant rally, but if we look at bitcoin, we can see it went from $16,000 to $30k in just 2 months. IMO, I don't think they are the same or have any big correlation.
