Cryptocurrencies are highly volatile, risky and complex products. Due to wide price fluctuations, trading them may result in significant loss over a short period of time. Leverage can work both to your advantage and disadvantage. As a result, trading cryptocurrencies may not be suitable for all investors, and you should never invest money that you cannot afford to lose.
In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash. Later, in 1995, he implemented it through Digicash, an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.
