O que são bitcoins e para que servem?
Could you please elaborate on what bitcoins are and what their primary purpose is? I've heard about this cryptocurrency but I'm still unclear on the fundamentals. Could you explain how bitcoins work? Are they like traditional currencies or are they something entirely different? Also, what are some of the main use cases for bitcoins? Are they primarily used for investments or can they be utilized for other purposes as well? I'm curious to understand how bitcoins fit into the broader financial landscape and how they're evolving.
