This method is easily defeated with gold-coated tungsten alloy. Like I said, portable XRF.

Edit: damn it justusranvier, you're quick on the trigger 

Anyone with more bitcoins than 1,000 is cautious of the rise, and scheming to keep the price in check to solidify their own position in the real world. (Anyone with <1,000 coins does not have walls)

Would a fake bar of gold ring different than a real one when tapped with a little hammer?

Fiat restriction creates demand.
How to get wealth out of China except bitcoin?

Me too!!!

Thanks guys, I was always interested for real when and if one day gold would be needed but there's bitcoin now

Gold isn't doing well mostly due to manipulation from the people who derive power from fiat emission and control. Mostly the families that own the banks and the fed.
They will probably come for bitcoin soon but manipulation will be much more difficult. They could buy lots of coins creating a spike and then dumping everything recklessly and crashing it, but I am not sure of their success. Gold is much easier to manipulate and discourage.

I am quite sure. It will be an utter failure, mostly for the reason that bitcoin would become public to all, and no matter how much short term damage they can cause, it will not be able to be kept down for long because its real network value is 1000x the exchange value. Only way they could wreak some havoc is by buying all the way to up, I mean 10,000x the current price, and then dumping it to the masses. But even that would be a win to Bitcoin. Everybody would use it from that on, and people who trusted in banks would have been made poor, and the independent thinkers enriched.

I agree that gold and silver are safer. At least as safe as your own physical safe !
But I don't think the run of gold to 1900 USD was a bubble at all.

how many do you have?..you still short? *wheres those $700 bitcoins now ? Lmaooo!
