Who we are
We are a passionate team of crypto-enthusiasts, technologists and educators dedicated to helping you navigate the world of Bitcoin. Our name reflects one of Bitcoin’s most important features — the hard supply cap of 21 million coins — and our mission is rooted in exploring that protocol in depth, from mempool to block header and beyond.
What we do
At 21 Million Bitco.in, we bring together a variety of resources all centred around Bitcoin
Faucet & Earn Directories

Educational Guides & Technology Deep-dives
From our step-by-step walkthroughs of how blocks are constructed, to detailed articles covering mining, Merkle trees, SHA-256 hashing, and more. For example, our “Bitcoin Mining Explained: From Mempool to Block Header Step-by-Step” guide covers unconfirmed transactions, Merkle root construction, block header fields and how mining works.
