現金によるローカルビットコイン取引とは何ですか?
Could you elaborate on the concept of local Bitcoin trading with cash? I'm curious to understand the process and how it differs from traditional exchange platforms. Specifically, how does one arrange a meeting with a seller or buyer, ensure the safety of the transaction, and what are the benefits and risks associated with this method of trading Bitcoin? Additionally, is it legal in all jurisdictions, and are there any specific guidelines or regulations one should be aware of before engaging in such trades?
