Digital currency markets have allowed themselves to be branded pejoratively whether intentionally or not. There is an interest in alternative personalities to brand using titles that reflect secrecy or criminality, for instance the Silk Road referencing kind of off-grid illegal trading.
There is also an interest to make these currencies synonymous with criminality in an effort to marr their reputation. Crypto and Dark Net could just as easily be sold on secure access and privacy. Instead, the nomenclature is spooky. Ether and Ethereum are awful names for a currency that should represent safety, privacy and innovation. Ether is something evaporating before your eyes, not a verbal representation of financial holding.
