When was Bitcoin created?

January 2007
January 2009
January 2010
January 2011

The correct answer is: January 2009

Bitcoin was created in January 2009 when its pseudonymous inventor, Satoshi Nakamoto, released the first version of the Bitcoin software and mined the genesis block, also known as Block 0. This event marked the beginning of the Bitcoin network and introduced the concept of decentralized digital currency to the world. The implementation of proof-of-work, which is integral to Bitcoin's operation, was part of this initial release, laying the foundational technology for blockchain that is now widely used across various applications and cryptocurrencies. The other options do not align with the actual timeline of Bitcoin's creation. January 2007 predates the release of any Bitcoin-related technology, while January 2010 and January 2011 occurred after Bitcoin was already in operation, with significant developments and awareness of Bitcoin emerging during those times but not its initial creation.
