1: Make quality post and soon your account will be earning ~50 Dollar per month - like me!

.
2: Dont gamble or invest in HYIP site.
3: Use faucets to collect "dust" for transaction fees - check out FreeBitco.in or Weekend Bitcoin and ... my site, BitRevenues.
$50 isn't enough though but pretty sure it should help. can you make it $50 a week by posting quality posts or is it possible to earn taht per week?
Yes $50 a week will be possible by posting quality posts on a campaign that has no limit of posts like this one on bit x but it will probably take a lot of time and effort as its not that easy to do especially when you have a limited knowledge on bitcoin

It's also kinda difficult cuz you'll may spam unintentionally.
But with the current exchange of bitcoins to usd, I think $50 is less difficult to achieve.
