I have tried working online with bitcoin as the reward and i think it's exciting coz it has a big currency exchange. But I haven't tried satoshi online currency yet, I think it's nice to have satoshis and I think it's fun to earn these rewards too. It's perfect to pay for ads that you wish to promote worldwide to get more members to your website who will join it, clients to order your online services. And you can buy digital products as well with your bitcoins or satoshis at the same time.
