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
Make sure you always double check or do it more before you send to the address, so you don't make any mistake. Sometimes we miss this, and we forget to check the address, or we only check the first character and the end of characters. That is why many of us still making a mistake, but from this, I think we need to always check before sending to another wallet.
