## Answers

### Answer by Hitesh Vohra

- The possibility of a cryptocurrency being used twice or more is known as **double-spending. I**f certain criteria are met, transaction information on a blockchain can be changed. If the prerequisites are met, updated blocks can be added to the blockchain, and the person who made the change can regain spent coins.
- When someone modifies a blockchain network and inserts a special one that allows them to reclaim a cryptocurrency, this is known as double-spending.
- Double-spending is possible, but it's more likely that a coin is taken from an unprotected and safe wallet.
