From beginner to advanced — master exchanges, wallets and blockchain essentials
Bitcoin is not made of metal or paper. It consists of code, blockchain records, cryptography, and network consensus.
Bitcoin is finite: its supply is capped at 21 million. The real question is how halving, mining, and network consensus keep that limit in place.
Why is bitcoin limited? Because its issuance rules were set at launch: supply tapers through halvings and tops out at 21 million coins.
Bitcoins come from protocol-defined block rewards created through mining, while fees come from coins already in circulation.
Bitcoin's founder is generally known as Satoshi Nakamoto, the name on the 2008 white paper and the creator tied to the 2009 genesis block.
As of August 1, 2026, estimates for how high will bitcoin go in 2026 range from $60,000 to $170,000 across public forecasts.
Is bitcoin worth investing in? It depends on your risk tolerance, time horizon, and whether you understand bitcoin well enough to handle its volatility.
Bitcoin mining refers to the process of adding new blocks to the Bitcoin blockchain using a consensus mechanism called proof of work (PoW) that requires the entire network to agree on the validity of transactions. Bitcoin miners around the world compete for the chance to add a new block and earn the block rewards paid in bitcoins. One recent block earned a 6.25 bitcoin mining reward plus 7.10 bitcoins in network fees. In this guide, we’ll explain how Bitcoin mining works as well as the pros and cons of mining Bitcoin.
