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?
Yes you will lose your coin and goes to someone else wallet and if you think this in real senior of world if you put your money to someone else wallet then it depends on the person in who`s wallet you have put the money whether he returns you the money or not. The only way you would have some chance with, is if you can find the owner of the wrong address that you sent your money to and try to persuade them to give them back and the odds of that happening is close to zero.
