But it could be possible to temporarily fake a human out and make them think they had real bitcoin which is all that is required for an effective counterfeiting operation. Eventually the sucker will find out their duped but by then the thief could be long gone.
I guess that would be possible... Everything is open sourced... If you compile a windows QT wallet and an node with a new genesis block, different ports, only your node, but the same GUI wallet... Mine some "bitcoins" with your new (fake) wallet, sell some "bitcoins" to somebody else using your own compiled (fake) wallet and cash in...
Your victim would have to be new, and very gullible, but i guess i could work in some cases...
Or am i missing something?
You could fake a transaction with your fake GUI "bitcoin-copy" in a café when trying to buy something and make it look like at first sight that you have the coins, but the transaction would never be confirmed in the real bitcoin network and therefore the buyer would probably never accept the "payment". All this would happen in your new coin's network and would never have anything to do with the bitcoin blockchain.
