What if someone made exact copy of bitcoin? Exactly the same way bitcoin works and created new bitcoins. Would the miners see it and not let the transations trough or is this possible?

Making an altcoin that has the exact same properties as bitcoin will fool no one. It will not appear on the regular blockchain and regular bitcoin client, and therefore will not be accepted. People also try to double spend which I guess is like counterfeit, but there is a solution to prevent this, wait for 1+ confirmations before sending goods.

No the longest chain wins Basically it would never catch up and be able to take over Bitcoin and the attacker could not delete the history of transactions up to the point of the attack, after they could only at most try to change the order to double spend. https://en.bitcoin.it/wiki/Weaknesseshttps://en.bitcoin.it/wiki/Myths#Anyone_with_enough_computing_power_can_take_over_the_networkThe only possible scenario would be a fork that users move to in the sense of XT but the coins would still exist on both up to the point of split. |

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" continiously with your new (fake) wallet(s), 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 cannot send someone a "fake" bitcoin because the transaction would never be relayed by any node or confirmed by any miner. |

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. |

100% true... But i'm not talking about buying something in a café. I'm talking about convincing your victim that your "fake" wallet is the real one. Let him use your "fake" wallet, send "fake" bitcoin from your own "fake" wallet to his "fake" wallet. In the meantime, run 2 or 3 miners (fake wallets, setgenerate true) to confirm your "fake" transaction from your "fake" wallet to his... Ask fiat or ALTcoin for the "fake" BTC you sent from your "fake" wallet to his... I know, it's far fetched, and it needs a really gullible, new, unexperienced victim, but it could work... And i think, technically, it could be called counterfeiting (or am i missing something?) |

and where are the miners to sustain it? people can't understand that are the miners that makes bitcoin strong, if bitcoin was pos, counterfeiting it was more possible, and that's why pos is flawed also they basically made it but in scrypt version, and no one took it seriously 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.

Your victim would have to be new, and very gullible, but i guess i could work in some cases... Or am i missing something? ehm he need to download your fake qt, you can't just build a clone and sent transaction to user with original core, it does not work in that way, and none will download it |

That's the beauty of bitcoin. You just can't make fake bitcoins. That's what makes it more real than the cash in your pocket.  |

If in another city lives somebody that looks like you and wears the same clothes as you, when he goes to his home, will your dog recognize him as being you? Nope, especially because your dog is in your home in your city, so they will never meet. (And also because the dogs use their nose, not their eyes, but that's another story.) I hope that's clearer now. |

that is impossible to cheat the blockchain because if that have any chance than it had already happened long time ago and don't come here to ask this question about it's possibility, BTCitcoin is the future of the currency that is not a fiat so there is no chance about that. |

I think it's possible to fool newbies with such fake BTC. Making a background infrastructure (network) is easy, you need a few nodes on cloud servers and a few miners with some old Block Erupters (you can get some for peanuts). The scammer will need some social engineering skill as well ("Are you using the right client mate? Oh I see, that's the old stuff, use this one and everything gonna be all right. You see? Here we go, your BTC is there now...") but I think it's doable on a small scale.

That's exacly what i was trying to say  . I guess the fact that i'm not a native speaker must have made my post a bit difficult to read... |

You can probably fool newbies just as you could fool them trying to sell gold-painted bricks as gold bars - you need to set up quite a bit of smoke and mirrors to hide the fact from them that you're not actually selling bitcoins.
Of course, people fall for the most obvious scams all the time (think of the "orphaned account" or bride scam stories) so there are probably people dumb enough to fall for this, too.

those bitcoins created on the fake bitcoin network can never be included in a block and would never be relayed by any node or confirmed by any miner. that would simply be an altcoin, which is happening everyday with a new name and a fancy announcement page! |
Weak hands have been complaining about missing out ever since bitcoin was $1 and never buy the dip.
Whales are those who keep buying the dip.

I don't believe this is technically possible. Because Bitcoin is decentralized it would be impossible for a hacker to insert malicious code into the network, there is no single node that controls the whole thing. Also the exact number of Bitcoins that can be mined in an hour/day is known and you can be sure that there are plenty people monitoring the network one way or another at any given time, especially those that have got 100 thousands of $ invested into their Bitcoin businesses  The owner of the pool you mine with could steal your coins though if he/she wanted to But that's unlikely  |

I had a similar thought: What if there was some way to counterfeit btc so that if you went to send it, it appeared ok, but would never process through the network. So say you went to meet someone and sell an item for btc. They "send" the fake btc to yoru address, everything looks good so you go your separate ways only to find out no btc were actually sent. I mean no one is going to sit around for an hour waiting for things to be confirmed. Is it possible this could happen? |
