Recently just got into 'investing' myself been doing a tonne of research so perhaps I could offer a bit of advice.
I've tried out:
cryptomulti.com/
http://cryptosrisk.com/home Both worked I would suggest going with the lowest earning options as they are much more likely to pay out.
Chainprofit - By the looks of it this isn't going to work out for me.
Vobank.biz - Just completed the 4% 42 hour deal made a whopping 35cents from a $10 investment lol. Trying out the 24hour deal as we speak hoping this will net me a little more profit.
https://cryptoconomist.biz/ - Just completed day 2 out of 20 so far so good.
Going to try out carbon7.cc and/or auto-profit.biz next I think.
Check out
