There is zero counterfeit bitcoin. You can't say the same about paper currency.
Technically correct, since bitcoin does not exist in physical form and therefore cannot be counterfeited in physical form.
But can transactions involving bitcoins be counterfeited? Most certainly!
Mt. Gox, Bitstamp, and other Bitcoin exchanges have temporarily suspended withdrawal transactions after coming under a form of a denial-of-service attack that abuses weaknesses in the way they keep track of fund balances, a security expert said.
Andreas M. Antonopoulos, chief security officer of digital wallet developer Blockchain, said the attacks work by flooding exchanges with a large number of malformed transactions that are similar, but not identical, to legitimate transactions that were already made. Exchanges that trust one or more of the fake records instead of the entries in the official Bitcoin blockchain quickly fall out of sync with the rest of the network and must recalculate their fund balances once the mistakes become apparent.
The net effect is the same. Counterfeit paper currency deprives its holders of the value of that currency. Counterfeit bitcoin transactions deprive the owners of the bitcoins involved in that transaction of the value of those bitcoins.
