This might seem fairly cruel, but I want to know if I can make a bitcoin packet with -1000 bitcoins in it.
As far as I can tell, usually, when you make a bitcoin packet, and somebody consumes it, however much bitcoin is transferred from your account to theirs. Well, I want to know if I could put -1000 in a bitcoin packet, so that when they consume the packet, they actually lose money, and I gain money.
