Bitcoin reached an all-time high of approximately $126,200 on October 6, 2025. The rally was driven by record institutional inflows into spot Bitcoin ETFs, the establishment of a US Strategic Bitcoin Reserve, and broader favorable regulatory developments. Bitcoin had previously crossed $100,000 for the first time in December 2024, following the approval of spot Bitcoin ETFs in January of that year. As of early 2026, Bitcoin is trading significantly below its all-time high. Cryptocurrency prices are highly volatile, and past price levels are not indicative of future performance.

Bitcoin's price is shaped by a combination of factors, including global liquidity conditions and central bank monetary policy, spot Bitcoin ETF inflows and outflows (which represent institutional demand), the Bitcoin halving cycle (which reduces the rate of new supply approximately every four years), miner economics and hash rate trends, adoption developments including corporate treasury strategies and sovereign reserve initiatives, regulatory actions across major markets, and broader macroeconomic conditions such as inflation, interest rates, and geopolitical risk. Bitcoin's fixed supply of 21 million means that price changes are primarily driven by shifts in demand, since supply growth follows a predictable and declining schedule. The factors listed above are for informational context only and should not be interpreted as price predictions. Nexo does not provide investment advice or price forecasts.

Bitcoin has a hard cap of 21 million coins, enforced by the protocol's code. As of early 2026, approximately 20 million BTC have been mined, leaving fewer than 1 million to be created through mining rewards. The remaining Bitcoin will be issued at a declining rate due to halving events, with the final fraction of a Bitcoin expected to be mined around the year 2140. An estimated 3 to 4 million BTC are considered permanently inaccessible due to lost private keys, forgotten wallets, or other irrecoverable circumstances — meaning the effective circulating supply is significantly lower than the total mined figure. This scarcity is one of the structural features most commonly cited in Bitcoin's long-term price discussion.

The Bitcoin halving is a pre-programmed event that cuts the block reward — the amount of new BTC miners receive for validating transactions — in half. It occurs approximately every 210,000 blocks, roughly every four years. The most recent halving took place on April 20, 2024, reducing the reward from 6.25 BTC to 3.125 BTC per block. The next halving is expected in 2028. Halvings reduce the rate at which new Bitcoin enters circulation, tightening supply growth over time. Historically, halving events have preceded periods of price appreciation, though past patterns are not guarantees of future performance and numerous other factors affect Bitcoin's price. After all 21 million BTC are mined, miners will be compensated solely through transaction fees.
