“Being open source means anyone can independently review the code. If it was closed source, nobody could verify the security. I think it's essential for a program of this nature to be open source.” - Satoshi Nakamoto

You bet! Open source is the way to go, especially for something as important as Bitcoin.
It means anyone can check out the code, spot bugs, and suggest improvements. It's a team effort that makes the whole system stronger and more secure.
If Bitcoin was closed source... well, I wouldn't trust it. And neither should you!
