it's still very odd to me how some people while making posts they will be using this statement "I don't know if anyone have talked about this or have created this topic before" like it is so annoying more especially when I see some higher rank members doing this
Higher rank doesn't mean they know everything about Bitcoin certainly they didn't read everything that has been ever written on this forum. Because it's more than 60 Million posts that need to be read if that's what you are trying to read. And also there are certain threads can exist in more than one section of this forum which is another reason why they start with such statements.
