❓ FAQ

What triggered the movement of dormant Bitcoin wallets?

The Coldcard hardware wallet hack is believed to be the primary trigger, as it may have exposed private keys of old wallets, enabling hackers or original owners to access and move the coins.

Does a dormant Bitcoin wallet moving coins always mean the coins are being sold?

Not necessarily. While often interpreted as a sell signal, it could also be a security measure by the owner—moving funds to a new wallet without immediately selling.

How does the Coldcard hack affect Bitcoin’s price?

The hack increases fear of large-scale selling if many compromised wallets are emptied. This uncertainty can lead to short-term price pressure as traders anticipate potential sell orders.
