There is no such thing as a safe investment. However, Bitcoin (BTC) does have a number of characteristics that make it relatively safer than other investments. For one, the total supply of Bitcoins is limited, so its value cannot be diluted by additional issuance.
Second, its decentralized nature makes it difficult for governments or financial institutions to manipulate its price.
Finally, Bitcoin has been around since 2009 and has withstood numerous hacks and setbacks, proving its resilience and security. Nonetheless, BTC's volatility make it risky for new participants.
