Proof-of-Work vs. Cloud Mining: The difference
If, as an investor, you are choosing between "Bitcoin Mining" and "Cloud Mining", you are not choosing between two flavors. You are choosing between an industrial operation and a contract with an unclear counterparty.
What Proof-of-Work actually is
Bitcoin secures its network through a competition. Whoever is first to find a valid hash solution for the next block receives the block reward (currently 3.125 BTC) plus the transaction fees of that block.
Finding this solution requires specialized hardware (ASICs) and energy. There is no shortcut. Whoever finds the block has done real work, in the form of electricity converted into heat.
A mining operation like Green Mining physically owns this hardware, runs it at real sites, and earns the block reward directly from the Bitcoin network.
What Cloud Mining claims to be
In cloud mining, the investor "rents" hashrate, usually in TH/s, from a provider. The provider claims to run hardware somewhere and pays the investor a share of the Bitcoin earned.
That sounds reasonable. In practice, the model breaks down for three reasons.
First: the investor owns nothing. He holds a contract whose performance depends entirely on the provider. If the provider goes bankrupt or disappears, the hashrate is gone.
Second: the contracts are typically structured so that under realistic assumptions the investor does not earn his deposit back. The math is asymmetric in favor of the provider.
Third: most cloud mining providers over the past ten years have either ended as Ponzi schemes or quietly shut down operations. Bitconnect, HashOcean, MiningMax, Power Mining Pool, the list is long.
How to spot the difference in a pitch
Three questions that a serious mining operator answers, and that a cloud mining provider typically does not:
First: where exactly is the hardware located? Address, power provider, contract duration.
Second: how are the machines financed, who owns them, and what share of them is allocated to the specific investor pool?
Third: who is the auditor, and when was the last audit carried out?
If any of these questions gets no concrete, verifiable answer, you are not in mining. You are in a debt relationship with a black box.
Why the distinction matters for you as an investor
If you want Bitcoin exposure, buy Bitcoin. That is cheap, transparent, and immediate.
If you want an operating business with cash flow that produces Bitcoin, you need a mining operator. That is an investment in assets, contracts, and staff, with all the advantages and risks of a real industrial operation.
Cloud mining offers neither. It is a third category, which in practice almost always goes wrong.
How Green Mining is structured
We are GM Data Centers AG, a Swiss stock corporation with a seat in Zug, commercial register entry, audited annual accounts, and real hardware in physically visitable facilities.
Investors hold shares in the company, not "hashrate contracts". We are the first tokenized company on Bitcoin, which means that the shares are held on Bitcoin-native infrastructure, with the legal clarity of a Swiss AG behind them.
In 2025 we produced 14.5 BTC and have been profitable since Q1 2025. Those are figures from an audited statement, not from a marketing dashboard.
A final note
Whoever sells you mining without hardware is not selling you mining. Whoever promises you guaranteed returns in mining has either not understood the business or is hiding something.
Real mining is an industrial operation with volatile, energy-dependent margins. That is precisely why it works.
