A $195+ mistake by not triple checking your btc destination address, and the amount being sent is an expensive lesson to be learned.
If you were sending a Bitcoin payment on your own and you by accident sent too much, there is nothing you can do about it. That money is gone for good.
At least here it is nice that there is a chance to get it back.
Although, in this case, I was in some sense paying myself, so I would have been able to just do a reverse transaction (and eat the fees).
