If you desperate to earn bitcoins or money, why not you should try to do a services in this furom. They can give you bitcoin if you doing what the services given to you. I think it is only a day or a week they paying you of your services of their campaign.
But that will not serve the purpose of getting money on the spot as by offering services or joining signature campaign you need to wait for certain period of time till you are not get paid so if you want money instantly then either you can borrow it from your friends or family or if you have some bitcoins then you can sell it and get converted to fiat money.
Must better to borrow money if you needed, Actually you can pay back the money you borrow when you have bitcoin if you are a familiar of bitcoin or you have account in this furom to participated in any campaign in here.
