Bitcoin runs on a simple, unbreakable rule: only 21 million coins will ever exist. That hard cap is a big reason it’s treated as the market’s anchor in the digital asset world, and by 2026 it’s been pulling in meaningful capital from Wall Street and other institutions.
Security comes from proof-of-work, where miners do intensive computations to protect the network and keep it honest. Bitcoin has lived through booms and busts, controversy after controversy, shifting regulation, and the same debates that never really go away. Hash rate, which reflects the total mining power pointed at the chain, has kept climbing even when profitability gets squeezed, and that persistence says a lot about long-term confidence.
