join some signature campaign , but 0.1 per week is hard i think
As I've seen in the campaign 0.1 iso hard to get in one week. As a new member I think you have to do multi task. Join signature campaign matching with skill working. Like translation, programming and etc. I've observe also other does a social activities to earn this. But if I would ask for this its really hard to earn in just one week.
It may look difficult to earn that much in BTC campaigns but I think you can earn more than that in altcoins campaign, I mean the legit altcoins campaigns. It may pretty much possible if you have a high ranked account and if the ICO became a success. Many dump their bounties on the day one after hitting exchanges if they keep it for some more months then they may earn good amount but yes it's depend on the good projects and not shitty ones.
