Bitcoin miners will still be paid after block rewards end, Simple Mining researcher says
One of the most persistent questions facing potential Bitcoin adopters is what happens when the network stops issuing new coins.
If block subsidies eventually disappear, will miners still have an incentive to secure the system?
According to Billy Boone, director of market research at Simple Mining, the answer is yes, and miners could become even more important over time.
How miners are rewarded
“A lot of people think that the block reward is just the block subsidy, but the block reward is the block subsidy plus the transaction fees,” Boone said.
That distinction becomes critical over the long term. Bitcoin’s block subsidy is designed to decline over time through halvings and will eventually reach zero around the year 2140.
At that point, miners will no longer receive newly issued Bitcoin for producing blocks.
What remains is transaction fees, and Boone argued those fees are directly tied to one of Bitcoin’s most underappreciated features: protocol-level scarcity.

Block space is scarce
Bitcoin’s blockchain has a fixed capacity. Only a limited number of transactions can fit into each block, typically just a few thousand. Boone used a stark example to illustrate the constraint.
“If all eight billion people in the world wanted to send a Bitcoin transaction, it would take like sixty years,” he said.
Rather than being a flaw, Boone views this limitation as a fundamental source of value. While most investors focus on Bitcoin’s 21 million coin supply cap, far fewer consider the scarcity of the infrastructure the coins move on.
“They do not understand that the rails at which the coins move on are blocks,” Boone said. “The limited scarce amount of space inside of a block.”
Miners as settlement providers
Bitcoin miners are effectively the producers of that block space. By choosing which transactions are included in each block, they perform final settlement for the network.
Boone compared miners’ role to that of traditional payment processors, which charge small fees on every transaction. Companies like Visa and Mastercard have built massive businesses on this model.
In Bitcoin, miners serve a similar economic function but without centralized control. They earn transaction fees by prioritizing transactions when demand for settlement is high.
Boone believes this dynamic will shape mining economics long before block subsidies disappear entirely. As Bitcoin adoption grows and block space becomes more valuable, transaction fees could increasingly drive miner revenue.
Rather than becoming obsolete, Boone said miners may evolve into pure settlement providers. In that future, securing the network is not a charitable act — it is a business grounded in scarcity, demand for final settlement and the economic value of block space.
