$2 billion worth of dormant Bitcoin since 2013 has reentered the market, sparking speculation.

The movement coincided with the approval of Bitcoin exchange-traded funds and the opening of the US market.

A large company, possibly Coinbase, is suspected to be behind the transaction.

The Bank for International Settlements observes that investors holding large cryptocurrency stashes often emerge as the biggest winners.

Despite recent approval of Bitcoin ETFs, the Bitcoin price is still down roughly 40% from its peak in November 2021.
