We have also seen that cryptocurrencies are not amenable to definition as a currency, asset or commodity; they have no underlying cash flows, they have no intrinsic value; that they are akin to ponzi schemes , and may even be worse. These should be reasons enough to keep them away from the formal financial system. Additionally, they undermined financial integrity, especially the KYC regime and AML/CFT regulations and at least potentially facilitate anti-social activities.
