A staff discussion note from the IMF (International Monetary Fund) urges banks to consider investing more heavily in cryptocurrencies. The note points out that cryptocurrency could provide benefits to the consumer in terms of trust, security, and privacy.

Trust Is Essential
The authors of the note stress the point that "trust remains essential." Consumers are relying less on the middle-man, and are interacting with more networks and providers than ever before. The note suggests that "policymaking will need to be nimble, experimental, and cooperative." In light of the constant news of cyberattacks and hacks, the authors of this IMF note believe that regulators might need to have increased governance over these issues in order to feel it is safe.
Regardless, it seems the transition to mainstream is happening. Slowly, but surely. It's not a matter of if it happens, but when and how.
