Santiment reveals that Bitcoin addresses holding between 10 and 10,000 BTC have sold 81,068 BTC in the past eight days, reducing their share of the total Bitcoin supply to a nine-month low of 68.04%. In contrast, retail addresses holding less than 0.01 BTC have increased their share to a 20-month high of 0.249%. This contrasting behavior highlights a shift in Bitcoin ownership from mid-size whales to small retail holders.
