Recent transfers of a substantial amount of Bitcoin from long-dormant wallets have sparked concerns in the cryptocurrency market, according to a report by CryptoQuant analyst Maartunn. The movement involved an estimated 8,000 bitcoins, valued at $674 million, transferred within a single block. This comes after a series of reactivations of dormant Bitcoin wallets. For instance, on March 24th, a bitcoin wallet inactive for 14 years moved 100 bitcoins worth $8.5 million. Early in March, six ancient bitcoin wallets transferred nearly 250 bitcoins, valued at $22 million. Typically, large transfers from long-term dormancy are interpreted as potential indicators of upcoming selling pressure, potentially leading to significant price drops. However, other possibilities for these transactions include internal wallet restructuring by institutional investors or large holders, and changes in cold storage arrangements.
