According to CoinMeta, the purpose of cryptocurrencies lies in enabling peer-to-peer value transfer and decentralized infrastructure. True cryptocurrencies allow users to securely send digital value directly to anyone in the world without the need for permission from banks or corporations. By adhering to their fundamental principles, cryptocurrencies solve significant problems in the real world: traditional bank international transfers take days and incur high fees, whereas decentralized networks can complete transactions in seconds at extremely low costs, demonstrating that digital currencies can enable fast payments without compromising on security. Furthermore, privacy-preserving networks protect users' personal financial information and prevent each digital transaction from being tracked. Decentralized artificial intelligence and computing power enable developers around the globe to jointly build open-source AI infrastructure that is not controlled by corporations. Traditional currencies can be infinitely printed by central banks, leading to a decline in purchasing power, whereas a mathematically fixed and carefully designed network provides an asset that is not subject to inflation, corporate board changes, or manipulation by insiders.
