Bitcoin hits 900,000 blocks on path to 21M limit
Bitcoin reaches 900,000 mined blocks
On Friday, the Bitcoin blockchain marked a significant milestone by reaching its 900,000th block. This achievement underscores Bitcoin's longevity and predictability, key attributes of its decentralized design.
The event has been widely celebrated across the crypto community as the network continues its march toward a fixed supply of 21 million BTC.
Key takeaways
- 900,000 blocks mined: A major milestone for Bitcoin, with block 1 million anticipated by mid-2027.
- Fixed supply: Bitcoin’s cap of 21 million coins remains intact.
- Next halving in 2028: Rewards will continue to shrink; eventually miners will rely solely on transaction fees.
- Long-term outlook: All blocks expected to be mined by 2140, surpassing 6.9 million in total.
A glimpse into Bitcoin’s future
According to blockchain data, it took just under two years for Bitcoin to advance from block 800,000 to 900,000. At this pace, analysts expect the 1 millionth block to be mined around May 2027. However, unlike conventional currencies, Bitcoin’s design includes a cap: only 21 million coins will ever exist. This limit, enforced by code, underpins Bitcoin's appeal as "digital gold."

The Bitcoin protocol reduces its block reward roughly every four years in an event known as "halving." The most recent halving occurred in April 2024, cutting miner rewards to 3.125 BTC per block. The next halving is projected to happen in March 2028 at block 1,050,000.
As these rewards continue to diminish, Bitcoin will gradually transition to a model where miners are compensated mainly through transaction fees rather than new coin issuance. This model is expected to reach full maturity around the year 2140, when the final block reward will be issued.
Price context and political overtones
Despite the technical achievement, Bitcoin’s price has come under pressure, falling 1.1% in the past day to $103,584. The slide is largely attributed to renewed political friction between tech magnate Elon Musk and Donald Trump.

The tension follows Musk’s criticism of a congressional spending initiative supported by Trump, with both sides exchanging accusations that spooked crypto investors.
A system designed for scarcity
Bitcoin’s capped supply remains one of its core value propositions. In contrast to inflationary fiat currencies, its predictability and scarcity continue to attract investors, technologists, and institutions alike. As of today, over 3 out of every 4 bitcoins that will ever exist are already in circulation.
With the mining of the 900,000th block, the crypto community celebrates not only an engineering milestone, but a reaffirmation of Bitcoin’s unique economic design. All eyes now turn to block 1 million—and to a future where Bitcoin's reliability may become more vital than ever.
