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?
If you send to the wrong bitcoin address of course the bitcoin will vanish. You will lose the btc you send and luck will get according to the address you input it. The lesson is that every time you want to transfer bitcoin must be very careful in entering bitcoin address. And if we need to send a bitcoin or coins / tokens we should be careful and double check if it's correct the address when you send bitcoin or altcoins
