To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens.

In other words, these are the coins that we think make the most valid investments (in general, not at a given moment) and are worth exploring for new coin users (not simply the coins with the highest market cap, value, or most relevance alone). With that said, any “best of” list is bound to have a bias, and this is true for this list as well. Feel free to make up your mind.

In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] 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.
