Key Cryptocurrency Risks and Fraud Prevention | A Must-Read Security Guide for Investors

1. Introduction: Cryptocurrency: Risks and Opportunities

Cryptocurrency is hailed as the "digital gold of the 21st century", but it is also a highly volatile asset full of risks.
Since the birth of Bitcoin, the market has experienced several ups and downs. While countless investors have made huge profits, some have suffered huge losses due to ignoring risks.
What’s more serious is that scams, hacker attacks and illegal platforms are emerging in an endless stream. If ordinary investors lack risk awareness, they can easily become victims.

2. Main Risks of Cryptocurrency

1. Market risk (price fluctuations)

• Bitcoin falls from $68,000 in 2021 to $16,000 in 2022

• Altcoins are more volatile, with frequent surges and plunges.

• If investors blindly chase high prices, they may suffer huge losses

2. Regulatory risks

• China bans cryptocurrency trading

• The US SEC frequently sues crypto projects and determines that they are securities

• EU MiCA (Markets in Crypto-Assets) regulations are establishing a compliance framework

• If investors use non-compliant platforms, their funds may be frozen.

3. Technical risks

• Smart Contract Vulnerabilities

• The wallet private key is lost and cannot be recovered

• Cross-chain bridges are frequently hacked (Poly Network, Ronin incidents)

4. Liquidity risk

• Some small-cap tokens lack trading depth, making it difficult for investors to cash out.

• Some exchanges even have artificial price manipulation

5. Platform Risk

• Centralized exchanges may go bankrupt or run away (FTX, Mt. Gox)

• Phishing websites trick users into entering mnemonics

3. Fake customer service and telecom fraud

• Scammers impersonate exchange customer service and ask users to transfer "verification funds"
