In the blockchain, bitcoins are linked to specific strings called addresses. Blockchain analysts estimate that Nakamoto had mined about one million bitcoins before he disappeared in 2010 and handed the network alert key and control of the code repository over to Gavin Andresen.

Bitcoin ownership is distributed among individuals, exchanges, institutions, corporations, and governments. As demand grows while supply remains fixed and decreasing, basic economics suggests upward price pressure over time, making Bitcoin attractive as a long-term wealth preservation tool resistant to purchasing power erosion. This scarcity is programmatically reinforced by the Bitcoin Halving, which systematically reduces the rate of new Bitcoin issuance, making it progressively scarcer over time as demand grows. This fixed supply ensures no central authority can inflate the supply or devalue the holdings of its users. This narrative has been reinforced by mainstream adoption, including the approval of spot Bitcoin ETFs and the acquisition of BTC as a treasury asset by major corporations. This behavior is not a flaw but a natural characteristic of a new, global asset class with unique market dynamics.
Bitcoin has not been premined, meaning that no coins have been mined and/or distributed between the founders before it became available to the public.

What Makes Bitcoin Unique?
Transactions are grouped into blocks, with each block containing a cryptographic hash of the previous block, creating an immutable chain. This ledger is distributed across thousands of computers globally, with each node maintaining an identical copy. The network maintains a public ledger called the blockchain, which records all transactions chronologically. Bitcoin operates as a decentralized peer-to-peer network where users exchange value directly without intermediaries. These coins have remained untouched since they were mined, and any movement would likely cause significant market impact. Nakamoto actively developed Bitcoin and communicated with the early community until mid-2010, when they handed over control of the network and disappeared from public view.
