Cryptocurrencies have become popular in recent years, but they carry significant risks that beginners should be aware of. The most prominent of these risks are:

1. High volatility: Cryptocurrency prices change very quickly, which can lead to significant losses in a short time.

2. Fraud and scams: There are many suspicious projects that exploit investors' ignorance to make illicit gains.

3. Loss of funds: If you lose the key to your digital wallet, it may be impossible to recover your money.

4. Lack of regulation: Many governments have not put in place clear laws that protect investors in this field.

It is important not to believe rumors about quick profits or fake guarantees, but rather to research and rely on reliable sources before investing.
