When it comes to regulation, we could take cue from Japan.
In April 2017, acting on the advice of the FATF, Japan revised its Payment Services Act.

Technically, Japan does not consider Bitcoin as legal tender because its not issued from any central government, but they do acknowledge that it can be used to purchase items.
