Não entenderam nada. Não se informam. E espalham inverdades sobre o Bitcoin.
"Para Sacchi, o primeiro elemento que configura o bitcoin como o ouro digital é a escassez. A moeda é o primeiro ativo a replicar o conceito de escassez no ambiente digital. A política de emissão é estabelecida no código do bitcoin e determina que ao todo vão existir apenas 21 milhões de unidades da moeda. “Isso faz com que o bitcoin seja ainda mais escasso do que o ouro. O próprio código de protocolo determina uma quantidade limite para extração que você pode ter diariamente. A cada quatro anos o limite da emissão diária deve cair pela metade, segundo o código”, diz o analista."

CONCLUSION
Bitcoin is scarce. That fact is not changed by its divisibility.
Of course, I am making those claims against the standard economic understanding of the term “scarcity.” But I think that any other reasonable sense of the term would have to draw the same conclusions. It would certainly require a rather strange understanding of the term “scarcity” to claim that bitcoin is not, in fact, scarce. One that is likely to be meaningless and unproductive for scientific analysis.
Bitcoin scarcity also has been increasing over time, despite that the system has been subject to monetary inflation. This is because demand for bitcoin has increased over time (though admittedly with some severe volatility).
I would expect this trend of increasing scarcity to continue, as its transparency, predictability, consensual nature, and censorship resistance make bitcoin a unique monetary asset. Though all of that is certainly not a given."
Bitcoin is obviously scarce. And it seems to be becoming scarcer over time.

"Why Bitcoin’s Hard Cap Will Not Change
Bitcoin’s hard cap is protected against change by its incentive system, as well as its governance model. Thanks to Bitcoin’s architecture, the entities who control Bitcoin’s rule set have strong incentives to resist a change to the hard cap, while those who may desire to change it have no ability to control the network.
Incentives
Miners are the actors who may have the strongest motivation to change Bitcoin’s hard cap. Changing Bitcoin’s hard cap may temporarily increase revenue for miners. However, doing so would destroy a core investment thesis for Bitcoin—its scarcity. For many investors, the allure of Bitcoin is the predictable, fixed supply. Wealth managers such as Paul Tudor Jones and institutions such as Fidelity Investments and BlackRock have credited Bitcoin’s scarcity as a significant motivation for its growing value.
Removing the fundamental driver behind Bitcoin’s value proposition is not in miners’ best interest. Although the change would increase miner revenue in bitcoin terms, the loss of faith in the Bitcoin network would result in a catastrophic and irreversible price collapse, leading to a net loss of miner revenue in fiat terms.
Since almost all miners pay their costs—equipment costs, salaries, and energy bills—in fiat, they are more concerned with their fiat-denominated revenue than their bitcoin-denominated revenue. Thus, if Bitcoin’s price crashes, miners lose.
Bitcoin Governance
Speculation that Bitcoin’s hard cap could change is rooted in two deeper misunderstandings about Bitcoin as a distributed, consensus-based network. Firstly, there is not one, but dozens or hundreds of versions of the Bitcoin source code. Every node in the Bitcoin network runs independent software that will reject any invalid blocks.
While many nodes run the latest version of Bitcoin Core, a significant number of nodes continue to run older versions and different implementations. Thus, while Bitcoin Core’s source code can be changed trivially, it is far more difficult to convince tens of thousands of nodes to adopt these changes.
Secondly, miners do not control the network or its rules. Miners produce new blocks and validate transactions. When miners submit a new block to the network, tens of thousands of nodes each independently verify this block, making sure it produces an appropriate amount of new bitcoin, includes a valid
Proof-of-Work, and all transactions within the block are valid. Nodes will reject all blocks that violate these rules, meaning miners have no control over Bitcoin’s ruleset.
This theory has been validated by reality, when, in 2017, 95% of miners agreed to raise the block size limit in an attempt to allow Bitcoin to scale. Nodes and users however, refused this change and successfully forced miners to adopt an alternative scaling solution.
How Bitcoin’s Hard Cap Could Be Changed
Despite the countervailing incentives outlined above, a supply cap change is still theoretically possible. In order to change the supply cap of Bitcoin, several groups would have to collaborate.
First, developers would have to propose and then write the code to implement this change. There would be community discussion, which would likely be controversial. If these changes were agreed upon by developers, the changes would be integrated into Bitcoin Core.
Next, the community would have to agree to an activation path, in order to ensure that the network transitioned to the new ruleset collectively. Changing the supply cap would necessitate a
hard fork, which means that all nodes on the network would have to adopt the changes or be forced off the network.
As part of the activation path, both miners and nodes would signal their support for the change, and once a dominant portion of the network signalled support, the change would be activated. Nodes and miners who refused the change would now operate a minority fork, preserving the original Bitcoin network, and the two networks would compete for market share and
hash rate."
There will never be more than 21 million bitcoin. This rule, encoded in Bitcoin’s source code, cannot be changed thanks to Bitcoin’s decentralized nature. If it were possible, changing this hard cap would destroy the value proposition of Bitcoin.
