the coin is lost due to a typing error or number I think it will not be sent, the address contract in each transaction must match that address. so the point is if you send it incorrectly because a letter error will not be sent or lost, unless you send it not because the error might be lost.
It seems a trivial thing, but it is important to know not to let us send the wrong address or to write something that will harm us, it requires precision in doing something
