    So long your shares are not sold by the system you earn satoshi if the site makes profit.
    Remember that you can only claim every 10 hours and so far the profit is low,it is speculation on the future.
    Once the profit is higher you can not claim more shares...what you get you get...
    Think about.
    And remember;
    The more shares you have...the less other shareholders have.
    This means that the part of profit is higher.
