i think Digital currency or more commonly known as cryptocurrency needs to be regulated as it needs to have features in olace that will protect us the consumer and those that would operate this from misuse and other kinds of fraud and Regulating cryptocurrency is not possible because it is decentralized but regulating the transactions in the cryptocurrency exchanges is possible and some governments have already imposed this kind of rules. The aim of regulation is to protect the bitcoin users from any scams that involved bitcoin and other cryptocurrencies and prevent some people in using it from any illegal acts
