Sorry for your loss. May I ask how much your loss was?
Did you send your Bitcoins to a valid address? In this case, your Bitcoins are not really lost. They are just owned by someone else.
I have lost my bitcoin yesterday, it happen because I sent my bitcoin to joining faucet but my mistake I don't read the rules of this faucet. when I deposit my bitcoin it is not adding my deposit in the faucet. so, I think my bitcoin is lost forever.
