Yes, Bitcoin is absolutely a part of web3. In fact, it can be argued that Bitcoin was one of the original web3 applications long before the term 'web3' even existed.

Web3 refers to the next evolution in the Internet - a decentralized version that reduces reliance on centralized servers and corporations. And Bitcoin's underlying technology, blockchain, enables peer-to-peer transactions without intermediaries and allows for total transparency in financial transactions.

Therefore, Bitcoin serves as a key building block for many dapps (decentralized applications) built on web3 technologies. It has become increasingly popular to build cross-chain infrastructure using smart contracts through Ethereum or alternative architecture such as Lightning network where there are countless innovative applications extending beyond payments through multisig wallets or distributed exchanges etc.

In conclusion – while Ethereum’s primary use case uses its Ethereum Virtual Machine as an all-purpose infrastructure stack from which more versatile blockchain utility-hosting dApp-s-deploying ones can be created with events notifications passing through central modules supposedly going to belong to some intermediate generic body such ENS (Ethereum Name Service) or [e.g.] Parity bridges and/or other structures directly connected into mainstream-WWW-backend/application pools like World Wire etc.Abstract each time coming closer irrespective of what genuine chain resides on top supporting crucial features everybody is vitally dependent close-to exact same goals coupled unlikely degree hosting essentially-ado HODL-states compartmentalized genesis-driven Sats-maximized Decentralized-Human existence.Loooots more than just Peer2Peer Cash ;)
