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?
It depends on your wallet because in our wallet coin.ph if you send a wrong adress you can contact the team of fheir company to resolve the problems but it takes a time because theyre are busy too so if you use like blockchain i think it never comeback again.
