Do you know how many Bitcoin has ever been counterfeited since10 years?
ZERO !There is no such thing as a "bitcoin" that can be copied. Rather, there is a list of all the transactions that have taken place on the bitcoin network and the order they have taken place. Every client has a copy of this list. Essentially, the only way to counterfeit bitcoins would be to spend them in more than one place. This is called a double-spend attack. However, because of the design of the bitcoin blockchain (the list of all the transactions) and the way that list is secured by mining, this requires a tremendous amount of computer power.
