Yes / • This article discusses the current situation in the market of cryptocurrencies and joins the debate about the regulation of these financial innovations. • It argues that the appearance of cryptocurrencies was a response to market demand for more affordable and more inclusive banking. • It also argues that distributed ledger technology (DLT) which supports cryptocurrencies and has different characteristics than the technology used by traditional banking could help to create with cryptocurrencies a new, lower cost, more inclusive financial ecosystem separate from the traditional one. • The two ecosystems (traditional and new one) would form a larger two-tier financial ecosystem, which, overall would be more inclusive and more affordable.

The costs of regulating the current market architecture are also excessively high.
