“Due to its use of blockchain technology, cryptocurrencies are unbreakable and unhackable.” That statement is not a fact, it is a challenge. As soon as someone figures out how to counterfeit cryptocurrencies, their value will tank and they will disappear. And counterfeiting cryptocurrencies won’t even be a crime since they are not supported by any pubic entity. It probably would not even fall under tort law, i. e., the counterfeiter probably could not be sued by anyone since no-one owns the technology.
N.B.: Any or all of the above might not be correct since I really don’t know what I’m talking (posting) about.
