Recent on-chain data reveals that the Bitcoin (CRYPTO:BTC) shark group, consisting of entities holding between 100 and 1,000 BTC, have engaged in their most significant accumulation activity in over a decade.

Analyst James Van Straten recently highlighted in a post on X that these Bitcoin sharks have acquired over 268,000 BTC in the last month alone.

This buying spree marks the largest since 2012, illustrating a substantial influx of investment into Bitcoin by this specific cohort.

The data underscores the growing confidence among these medium-sized Bitcoin holders, as they significantly increase their stakes in the cryptocurrency.
