The Quantitatively-Flexible Electronic Reserve Currency

bitcoinR is a decentralized electronic reserve currency with a centralized, periodic open-market-operations function designed to stabilize against substantial fluctuation.

What is bitcoinR?

bitcoinR is a hybrid peer-to-peer transaction platform with decentralized nodes & centralized governance.

The bitcoinR currency (XBR) was created to serve as the global-reserve-cryptocurrency with a fixed supply and transparent valuation. 

When recognized by the wider market, these cryptonomic pegs provide underlying economic stability designed to promote the exchange of human work for monetary value.

bitcoinR: What does the "R" mean?


We believe in a capped money supply, but one that can be adjusted quantitatively.

A "reserve" currency is a currency that is held in significant quantities by central banks or other monetary authorities as part of their foreign exchange reserves. The reserve currency can be used in international transactions, international investments and all aspects of the global economy.

bitcoinR via XBR, LLC has self-selected into government regulation in the United States of America.  We opted to become regulated as an MSB in the largest capital market on the planet as a means to encourage participation with and faith in the bitcoinR network and associated XBR digital currency.

We expect this to encourage enthusiastic participation by individual citizens as well as regulated entities such as banks, financial services firms, funds and insurance companies.


As administrators of the XBR currency, we are regulated by the U.S. Dept of Treasury.

Three Methods of XBR Acquisition



XBR is a virtual currency, not a security and therefore may only be purchased via a Virtual Currency Exchange (VCE).



XBR may be acquired through the provision of human effort against a "bounty" or need posted by the bitcoinR network.
