Well last weeks net transnational revenue of 17,000 euro worked out at about .31 euro per 1 million BNK held. So if we can generate revenues of 170,000 per week when cards are up then that's a not too shoddy 3 euro a week return. @ $1,855 USD per 1million BNK, that would give you:
52*3 = 156 Euro per year so around an 8% return on investment over a year! Far better then any bank is going to give you!

Exactly people are too focused in some $hitty dream of "I invested 20$ get me my 20 Millions $" well I see it in terms of ROI and % and that is high once you compare it to any Bank and furthermore given the Banks in Stocks, I don't see them going to make their ROI better, so everytime I can I Dollar Cost average on BNK
