Bitcoin technology, including protocol and cryptography
, has a strong security record, and the Bitcoin network may be the largest distributed computing project
in the world. The most common weakness of Bitcoin
is user error. Bitcoin wallet files that store private keys
can be accidentally deleted, lost, or stolen. This is very similar to physical cash stored in electronic form. Fortunately, users can use a solid security policy to protect
their funds, and they can also use a provider that offers a good level of security and insurance against theft or loss.
