The wallet has a significant level of security for it users
Bitcoin Core wallet is compatible with Tor, an anonymizing service that can hide users’ IP address. It can also make it difficult for third parties to track down transaction details.
All transactions carried out to and from any wallet on Bitcoin Core go through a large peer-to-peer network. As such, it is much harder to track individual users’ transactions than it would be on a lightweight peer-to-peer client.
The wallet automatically generates a tree of keys for its users. Users can access this using a 12- or 24-word phrase based on the tree.
