“Making money with cryptocurrency” groups together very different activities. Buying an asset, operating mining equipment and selling a digital creation involve different requirements and risks. Before assessing an income claim, try to explain where the money would come from and what happens if the expected outcome fails to materialize.

Trading: a price rise is not the same as profit
A green figure on a screen does not describe an investment’s complete result. You need to know what you paid in, what you can recover and the transaction costs. An advertised price may differ from the price at which you can ultimately sell.
For example, in a simplified scenario, buying for €100 and selling for €110 leaves €10 before costs and taxes. If costs were €12, there would be a €2 loss before taxes. This is an arithmetic example, not a forecast or a real fee schedule. Trading more frequently does not remove that distinction.
Mining: competition with operating costs
Bitcoin.org’s documentation describes mining as computational work that participates in the network and can earn rewards; it warns that profits are not guaranteed. Assessing a proposal means including equipment, electricity, maintenance and service conditions. Multiplying an estimated reward by the asset’s current price is not enough.
If someone sells a mining contract, ask for a verifiable explanation of what you are buying, who operates the equipment and what happens when costs exceed revenue.
Staking: examine the network and intermediary
Rules differ between networks and services. Ethereum.org explains that staking pools introduce dependencies on third parties. Risks include penalties, contract failures and liquidity problems. A liquid staking token can trade below the value of the asset it represents. Not everything marketed as “staking” is direct participation in the protocol.
Compare the currency in which returns are expressed, fees, withdrawal conditions and who bears losses. More units do not guarantee more euros. For another example, read our explanation of Cardano and ADA delegation.
NFTs: publishing guarantees neither sales nor royalties
Creating an NFT does not establish demand for it. Before spending money to publish one, clarify the rights you are offering, your costs and the marketplace rules. OpenSea distinguishes optional and enforced creator earnings according to settings and contract compatibility. It is incorrect to say every creator automatically receives payment on every resale.
A short checklist for evaluating a proposal
- Who pays the return, and which activity generates it?
- Which costs are deducted, and which would I pay separately?
- Who controls the assets, and under what conditions can I recover them?
- Can I afford to lose the money or lack access when I need it?
The European Supervisory Authorities recommend checking provider authorization and stress that protection depends on the asset and service. Regulation does not turn an offer into assured income.
