1. Ponzi Schemes
A Ponzi scheme is a type of fraud where funds from new investors are used to pay returns to earlier investors, rather than from profit earned by the operation of a legitimate business. Ponzi schemes are unsustainable and usually collapse after a short period.
How a Ponzi Scheme Works:
New investors are attracted by promises of high returns, but no real investment is made. Instead, the money from new investors is used to pay old investors. Such schemes tend to grow rapidly, leading to large losses once they collapse.
Ponzi Schemes in Cryptocurrency Markets:
In the crypto space, Ponzi schemes often appear through new, unknown altcoins or ICOs (Initial Coin Offerings). Projects promising high returns to investors are often nothing more than scams.
2. Phishing Attacks
Phishing is a type of attack where fraudsters send fake messages, pretending to be from trusted sources, to steal personal information. Cryptocurrency users are frequently targeted by phishing attacks. These attacks are typically carried out through fake emails or websites.
Methods of Phishing Attacks:
Email Phishing: Fraudsters send fake emails to steal users' passwords or private keys.
Website Phishing: Fraudsters create fake cryptocurrency exchanges or wallet sites to steal login credentials.
SMS Phishing (Smishing): Fraud attempts conducted through phone messages.
Phishing in Cryptocurrency Markets:
Cryptocurrency investors are prime targets for phishing attacks, as fraudsters attempt to gain access to wallet and exchange accounts. Investors need to be cautious about clicking links from unofficial sources.
