On February 4th, BTC has fallen from the high of $97,000 on January 15th to $73,000; the speed is fast, and the magnitude is deep, instantly extinguishing the optimistic sentiment that originally thought there would be resistance at 80k. To say there is no panic would be a lie. Therefore, it is necessary to review what changes have occurred in BTC's chip structure during this period and what important information is hidden behind it.

For ease of understanding, I have compiled the complete URPD data into a table, using each $10,000 interval as a section, allowing for a clear observation of the trajectory of chip movement to assess current market sentiment and behavior.
