Hi!
As the title says, what happens if i get an address wrong? Do the coins get lost?
If that's what happens, why not change the code in Bitcoin, so that if the bitcoin network cant detect that address, returns the bitcoins to you?
We know that bitcoin is that technology which is famouse for its two quality that is reliability of payment that can't reverse and has not limit to transfer .
So here no chance for you to get back your bitcoin ( sometimes fees factor for long term unconfirmation results into reverse of bitcoin but I had never faced such things in my bitcoin work career ) .
And also sometimes when we send bitcoin to wrong address then bitcoin doesn't transfer ( I am talking about mistake type any extra word , or erase of any word or type of equal word ) .
Hope you understand well that what are probability that can happen with you .
