Could Bitcoin’s Supply Cap Be Changed? BlackRock Sparks Debate

A new wave of controversy has emerged surrounding Bitcoin's 21 million supply cap, triggered by a recent BlackRock video.

While the financial giant reiterated the importance of Bitcoin’s fixed supply in maintaining its value, it also introduced a caveat—stating that there’s no certainty the cap will remain unchanged in the future.

Bitcoin’s capped supply has long been considered a critical aspect of its value proposition as a store of wealth. The idea that this limit could be altered has unsettled many in the crypto community, leading to concerns about its impact on investor confidence.

BlackRock’s video , intended to explain Bitcoin’s fundamentals, stressed the role the cap plays in protecting against inflation and maintaining purchasing power. But the added disclaimer suggesting a possible future change has raised doubts about its permanence.

Some critics, including figures like Joel Valenzuela of Dashpay, argue that the cap’s potential modification would be seen as an inevitable shift, signaling a departure from Bitcoin’s original design. This has prompted further debate about what constitutes “real” Bitcoin.

According to some developers, changing the supply cap would require a consensus-driven hard fork, where a majority of the network supports the change. However, even if such a fork were successful, many argue that it would result in a new version of Bitcoin, no longer adhering to Satoshi Nakamoto’s original vision.
