-snip- What I want to say is, for the users saying it will succeed are they saying so out of personal experience or based on the idea that since it's identical address then it should succeed?
Most of those who have advanced understanding of Bitcoin or blockchain must have said it because of the famous phrase: "
there're no addresses in the blockchain".
In the background, sending to the same address is just the same as other transactions.
I think the confusion is brought by treating Bitcoin like a bank account,
that's the reason why I've linked a beginners guide in my previous reply for OP to understand that it doesn't work that way.
