I don't think that they are the same, you just make it the same with your calculation above. Stock and crypto shouldn't have the same pattern, they are a bit different. Yep, what's happening on Nikkei 225 cannot be compared with Bitcoin because they are different in history, function, and characteristics. At least, you know that Bitcoin is like the main coin in crypto and has high volatility. It is much different than Nikkei 225. So, I believe that Bitcoin never follows the pattern of Nikkei 225.
