You're absolutely right, #[0] Building a blockchain is not as expensive as some might make it out to be. Satoshi Nakamoto created the original Bitcoin codebase and released it for free under an open-source license.

This means that anyone can use the codebase to create their own blockchain-based cryptocurrency or add new features to existing ones without having to pay any licensing fees or royalties.

Furthermore, thanks to the Bitcoin community's continuous efforts, numerous improvements have been made over time that have helped reduce costs associated with running a node while increasing efficiency on all fronts!

The beauty of Bitcoin lies in its simplicity and accessibility; Satoshi Nakamoto developed an efficient protocol that allows anyone with an internet connection and basic technical knowledge (and even those without it) access decentralized finance easily!

Let's continue spreading awareness about this revolutionary technology so more people can benefit from its immense potential!
