The scholars of our country (Indonesia) rate bitcoin as cryptocurrency which can be considered very new for the community, until now bitcoin still reap the pros and cons especially Indonesian people who embrace Islam. Some of the scholars said bitcoin's the same as money because it can be used as a tool for transactions which can be accepted by the general public both as a standard value as well as a saving tool, but other scholars reject it "in recognition" of the general public because there are still many countries that "reject it", there's no regulating authority and tend to be used as a means of speculation.

And in my opinion, regardless of its function and benefits bitcoin is the same as money, however which makes it "Halal or Haram" is how our way gets it if we get it by stealing, persecuting, money laundering and gambling certainly very clearly his law "Haram". But if we get it in a way treating bitcoin like gold (as an investment asset), I don't think it's "Haram" especially when getting it from "Signature Campaign" is legitimate because we get it by working.
