Bitcoin Mining: How It Works and Where the Yield Comes From
Bitcoin and Mining — Where the Yield Really Comes From
Before talking about GoMining, we need to understand what is actually being purchased: not a promise of returns, but productive capacity connected to Bitcoin mining.
When people talk about Bitcoin, most attention goes to price.
I chose to look at another side of the ecosystem as well: the process through which new BTC are issued and transactions are secured.
This is where my GoMining journey begins.
What is Bitcoin mining?
Bitcoin uses a consensus mechanism called Proof of Work.
Miners provide computational power and compete to produce valid new blocks.
This activity performs two essential functions:
- it contributes to network security;
- it allows new transactions to be recorded on the blockchain.
The miner that successfully produces a valid block receives an economic reward.
Where do miners' BTC rewards come from?
A Bitcoin block reward mainly contains two components.
After the 2024 halving, the block subsidy is 3.125 BTC per block.
This amount will not remain constant forever. Bitcoin periodically reduces issuance through halving events.
Mining economics therefore change over time: block rewards, network difficulty, global hashrate, energy costs and Bitcoin's market price all influence the outcome.
The key idea: mining is production
When I buy Bitcoin directly, I am purchasing an existing asset.
When I buy mining capacity, I am instead buying exposure to a productive activity designed to generate BTC over time.
Buying BTC
Capital → BTC purchase → ownership of the asset.
The economic result depends mainly on how the value of the Bitcoin held changes.
Producing BTC
Capital → mining capacity → progressive BTC production.
The result also depends on efficiency, mining difficulty, operating costs and the amount of BTC produced.
Mining means owning productive capacity designed to generate BTC.
Hashrate: productive capacity
Mining power is normally measured through hashrate.
In the GoMining course we will mainly use TH/s, or terahashes per second.
In simple terms, more TH/s means more computational capacity dedicated to mining.
But accumulating TH is not enough to build a strong strategy.
The cost of maintaining that productive capacity matters just as much.
Efficiency: why W/TH matters
Mining consumes energy.
That is why another important metric is energy efficiency, often expressed as watts per TH.
Better efficiency means using less energy for the same amount of computational power.
This relationship becomes crucial when analysing GoMining, because what matters is not only how much BTC is produced.
What it costs to produce it matters too.
Mining does not produce guaranteed returns
Production does not mean certainty.
Mining results can change because of:
- network difficulty;
- global hashrate;
- halvings;
- Bitcoin transaction fees;
- energy and maintenance costs;
- BTC price;
- infrastructure efficiency.
For this reason, I do not believe mining should be judged from a single yield percentage shown at one moment in time.
Why this matters for GoMining
GoMining does not create Bitcoin through a financial formula.
The model starts from mining capacity represented by Digital Miners and connects that capacity to BTC production.
This is why, before analysing GOMINING, maintenance, VIP or reinvestment strategies, we first need to understand the underlying engine.
What to take away from this lesson
- Bitcoin mining is fundamental to network security;
- miners receive BTC through block subsidy and fees;
- buying BTC and buying mining capacity are different strategies;
- TH and W/TH describe capacity and efficiency;
- gross production is not the same as net return because costs matter.
This leads directly to the next question: if I want to produce Bitcoin, do I really need to buy and manage a physical ASIC myself?
