                                      SatoshiPay                                   

    Coinsilium Group Limited (NEX:COIN), the blockchain technology investment and
    development company, is pleased to announce that SatoshiPay Ltd ('SatoshiPay'),
    a Nano-Payments company in which Coinsilium has a 14.5% equity interest, has
    entered into a conditional agreement with investing company Blue Star Capital
    plc (AIM: BLU) which has conditionally subscribed for 1,886 ordinary shares in
    SatoshiPay for €0.64 million.

    Details of the announcement from Blue Star Capital can be seen here: http://

    13095677.html

    If completed, this subscription would value SatoshiPay shares at €340 per
    share.

    In January 2016, Coinsilium completed an investment of €200,000 and holds 2,133
    ordinary shares in SatoshiPay via Seedcoin Limited, Coinsilium's wholly owned
    subsidiary.  Should the Blue Star subscription complete, at €340 per share the
    implied value of Coinsilium's shareholding in SatoshiPay would be €725,220,
    representing an increase in value of 362.61% since Coinsilium's investment less
    than a year ago.

    Coinsilium CEO Eddy Travia commented: "We are delighted to see the interest
    SatoshiPay is generating amongst early stage technology investors and whilst
    this subscription comes at a substantially higher valuation than that of
    Coinsilium's original investment, we also recognise the significant progress
    SatoshiPay has made over the last year to justify such a substantial uplift in
    its valuation. This subscription underscores our early vision that SatoshiPay's
    blockchain-based platform can transform online content monetisation and further
    proves our well-founded confidence in SatoshiPay's CEO Meinhard Benn and his
    excellent team as leaders in this space."
