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
It requires presence of mind before sending your tokens/coins to another wallet address, you have to double or triple check each information that you needed to remember, failing to do so will results to lose your coins forever, I was once experienced this transferring coins to a wrong address and never
recover anything back.
