Well you can now earn USDC for doing surveys through PublishOX...
However personally I'm not that tempted - for starters the rates are well below minimum wage..... at around $0.60-70 for 10 minutes work that's like $3-5 an hour, even if you're just dicking around on the computer at home and it's not really 'work' as such.
However even less appealing is giving all yer data away before you can participate to earn yer derisory hourly rate...
NB not my actual DOB!
And the next box asked me for my postcode, at which point I just shut the window and decided I'd stick to blogging.
Anyways, if you are a bit more desperate for money and can't earn enough through a regular job, then this is an option for earning I guess!
NB ATM this is in BETA so may not be accessible to everyone, possibly something of a wait and see!
