Big investors who have been holding onto Bitcoin for years have started moving their holdings, including wallets that have been dormant for over a decade. In one case, a Bitcoin whale transferred over $37 million worth of BTC to a new address after 11 years of inactivity. These investors, who hoard at least 1,000 BTC, have proven to be more successful than short-term traders due to the cryptocurrency's extreme volatility. It is unclear whether these whales are individuals or companies, but some may be commercial entities buying Bitcoin from individuals.
