Bitcoin holders with balances between 100 and 1,000 coins have accumulated a record 3.65 million Bitcoin, according to blockchain analytics firm Glassnode.

These investors, termed “sharks” by Glassnode, added approximately 65,000 Bitcoin to their holdings over the past seven days. The buying pace has accelerated, with this group recording a net increase of 93,000 Bitcoin over the past 30 days.

The accumulation pattern represents the highest total holdings on record for this investor category, which sits between smaller retail investors and large institutional holders or “whales” that typically hold more than 1,000 Bitcoin.
