protocols and cryptography have a strong security record, and the Bitcoin network is probably the largest distributed tally project in the world. The most common disadvantage of Bitcoin lies in its user error. Bitcoin wallet data that stores private keys can be accidental, lost, or stolen. This is similar to physical money stored in digital form. Fortunately, users can apply security measures to protect their money or use the services of providers that offer high levels of security and insurance against theft or loss.
