Can you buy things with Bitcoin?

Could you elaborate on the feasibility of purchasing goods and services using Bitcoin? As a cryptocurrency enthusiast, I'm keen to understand if it's truly practical to utilize this digital currency for everyday transactions. Could you discuss the extent of Bitcoin's acceptance among merchants, as well as any potential limitations or challenges associated with its use? I'm also curious to know if there are any specific types of goods or services that are more commonly purchased using Bitcoin, and if there are any security considerations to be mindful of when making such purchases. Thank you for your insights.
