Cryptocurrency — What It Is and Why Caution Matters
You may have heard of Bitcoin, Ethereum, or crypto investments. Here is a clear, honest explanation.
What is cryptocurrency?
Cryptocurrency is a form of digital money that:
- Exists only online — there are no physical coins or notes
- Is not issued or controlled by any government or central bank
- Is stored on a blockchain — a shared digital ledger maintained by computers around the world
- Has a value that changes constantly, sometimes dramatically
Bitcoin is the most well-known cryptocurrency. Others include Ethereum, Solana, and thousands of smaller ones.
Why do people use it?
Some legitimate uses:
- International transfers — sending money across borders quickly and cheaply
- Store of value — some people hold Bitcoin as a long-term investment (very high risk)
- Decentralisation — not subject to government control in certain countries
The serious risks
1. Extreme price volatility Bitcoin lost 65% of its value in 2022 in a matter of months. It can rise and fall by 20% in a single day. This is not suitable for money you cannot afford to lose.
2. No insurance or protection Bank deposits may qualify for deposit-protection schemes, subject to local rules and limits. Crypto holdings generally do not receive the same protection. If an exchange fails or a wallet key is stolen, recovery may be impossible.
3. Scams and fraud Crypto is the preferred payment method of scammers because transactions are irreversible. Once you send crypto, it cannot be recovered.
4. Complex and easy to lose Lose your “wallet key” (like a password) and your crypto is permanently inaccessible.
What financial regulators warn about
Financial regulators repeatedly warn that crypto assets can be highly volatile, difficult to value, and exposed to scams or platform failures. Regulation varies by country and does not make an investment safe. Check your financial regulator’s warning list before sending money to a platform.
How crypto is used in scams
Investment scam: Someone contacts you (often online) about a crypto investment platform with guaranteed high returns. You invest, see “profits” on screen, but when you try to withdraw, you are asked to pay fees. The money is never accessible — it is a scam.
Deepfake celebrity endorsements: Fake videos of public figures (ministers, celebrities) promoting crypto apps. These are fabricated.
Romance scam leading to crypto: A new online “friend” eventually suggests you invest together in crypto on a specific platform — which is controlled by the scammer.
If someone recommends a crypto investment
- Stop. Guaranteed returns do not exist in crypto.
- Search your financial regulator’s website for warnings about the company or platform.
- Check that you can identify the legal company, jurisdiction, fees, and withdrawal rules.
- Report suspected fraud to your bank, financial regulator, and local scam-reporting service.
