Is bitcoin considered money according to Torah Law?
There is no Halachic objection to the recognition of a virtual currency - if it would be accepted as a currency by a state. A currency which is publicly trusted and viewed as a means of payment, and an assessment unit may be considered Halachically as a currency even if it is not officially recognized by state authorities - at least in regard to payments etc. The Bitcoin was not issued by a state, and has limited public trust. Therefore, in the current situation it is not recognized as a currency according to Jewish Law, but rather as a commodity or debt bond. Source: Summary of Rabbi Shlomo Ishon’s article on the topic.
