Should Cryptocurrencies Be Regulated like Securities?

"Cryptocurrencies are a new and promising technology, the benefits of which remain little understood and hotly disputed. Policy uncertainty and ambiguous statements by financial regulators further complicate an assessment of the risks and rewards that ownership of this asset class can bring."
"Yet, the answer is not to clamp down on cryptocurrencies. Volatility, as long as it is not caused by fraudulent or illegal market behavior, is not a regulatory concern. Rather, the goal of regulators should be to provide confidence in the stability of the regulatory framework by defining how cryptocurrencies fit within existing rules. Such regulatory certainty need not come at the expense of the accessibility of blockchain technology to firms and individuals."
