I will try to be as coherent as I can, so bear with me on this but, no 
matter what, I will be as honest with you as possible. Those below are 
the websites I use to earn my booze money:
MTurk - Probably everyone knows about it. It has something for everyone: if 
you want to do only surveys, you have enough of them to keep you working
 at least one hour every day. If you want to do data entry HITs, just go
 for it! Like I said, there’s plenty for everyone. However, you have to 
know how to find those HITs that are indeed worth turking for. My 
strategy? I knock out everything I can find on the HWTF section, then I 
search for anything that I’m qualified for and is over one dollar. After
 that, I search again for “survey” or “study” that pay not less than 25 
cents. Bu doing this, I can easily earn about $100 each week with about 
two hours of turking each day. You can use your money either to buy 
Amazon gift cards or transfer them into your bank account. Easy-peasey.
Topline -

 - This is the purest passive earner there is. The principle is this: 
you sign up, install their plugin for your browser and just continue 
surfing, as usual. This plugin replaces any ads with some of theirs and 
you get paid for it. Simple, huh? Vewy. They have a point-based system 
and for each website you visit that incorporates ads you get one point. 
For every 1000 points, you get $0.75. It may not sound as much, but 
given the fact that you do nothing is convincing enough, at least for 
me. Also, the minimum cashout is at $10, which can be achieved in about 
2-3 months of surfing, without having any referrals. Also, for each 
referral you earn 5% of the points they earn. The money can be cashed 
out to PayPal.
NeoBux -
 Ref | 
Non-ref
 - A very intriguing PTC (Paid-to-Click) website. If you’re not familiar
 with the concept, what you have to do is click a given number of ads 
each day, for which you get a very small amount of money. Neobux offers 
you the possibility to 
rent referrals for a certain 
period of time, during which you get a sum of money based on how many 
clicks they have each day. Of course, there is the classical concept of 
direct referrals too, but, obviously, you don’t earn much from them, 
unless you get to have a large base of active referrals. Anyway, back to
 the rented referrals. This system gives you a lot of new opportunities,
 because you get to make decisions like recycling a certain referral if 
they have bad stats or adding more time to their renting period and so 
on. Also, for each ad you click you get three chances to the so-called 
“AdPrize” The prizes vary from points, cash or even Golden membership 
(which, believe me, is welcome anytime). Anyway, if you want to go deep I
 strongly recommend you their 
FAQ. The minimum cashout is $2, to PayPal, Payza or Neteller.
ClixSense - 
Ref | 
Non-ref
 - Another PTC website, but this one is not based that much on renting 
referrals. If you don't want to take your chances renting referrals that
 may or may not be productive, Clixsense is based on direct referral 
revenue and mini-tasks. More specifically, it incorporates the 
CrowdSource working platform, so you have work to do 24/7, even if the 
pay is not that good. If you get a decent number of direct referrals, 
you just have to click your ads every day (takes a few minutes) and 
that's it. Also, there are offers to complete, plus a nice mini-game 
called ClixGrid - very much like Neobux' AdPrize, if you're lucky you 
can win cash or points. You can then cash your money out to PayPal, 
Payza, Liberty Reserve or check. The minimum payrates can be found 
here.
Naturebucks - 
Ref |

  - NatureBucks is a pretty straight-forward website. Here, you can 
complete various “offers”, which mostly consist of surveys or 
registering. You can even find a dedicated section to the best offers 
there are, 
here 
on reddit. Anyway, by completing those offers you earn either cash or 
points, which can be eventually transformed into cash too. The minimum 
withdraw is of only 5 cents to Paypal, or $1 for Amazon gift cards. 
Also, the 5-tier referral system is great if you can get a decent number
 of direct referrals, because you earn 20% from your level 1-5 
referrals.
NatureGPT - 
Ref |

 It’s pretty much like Naturebucks. You have a list of offers (mostly 
surveys) you can complete for either cash or points. Somehow, I even 
like this better than Naturebucks, because for each referral that earns 
at least $0.25 you get $1, bur only one time per referral, plus, of 
course 20% of what they earn next. You can then withdraw your cash to 
Paypal or use it to buy Amazon gift cards. The minimum payout is $2, 
which is decent enough in my opinion.
PaidViewpoint -
 Ref | 
Non-ref
  - Another survey site. Their surveys don’t pay very much, but you get 
about $1 only for completing you profile. After each survey you complete
 your so-called TraitScore also increases. How does this help you? After
 your TraitScore reaches a certain threshold, the amount of money you 
earn per each completed survey will increase. Don’t expect to earn 
hundreds of dollars every month, but if you complete a survey every now 
and then they will start pilling up. However, the minimum payout is of 
$25 to Paypal, which can be a bit disappointing for some of you.
Pollbuzzer - 
Ref | 
Non-ref-
 Very nice survey site. There are not any offers available, but you get a
 mail from them every now and then asking you to complete a short 
survey, worth $1. It does take just a few minutes, which is definitely 
worth the time, even if there’s not much to do. You can cash out your 
earnings to PayPal.  Also, each time one of your referrals answers 4 of 
these polls you get one dollar.
CloudCrowd -
 Ref | 
Non-ref
 - It's a pretty good cloud working platform. You don't always find too 
much work to do, unless you do writing. But first things first. In order
 to do writing, you have to earn some credentials first, depending on 
what type of writing you want to do. I only applied for the marketing 
credential myself only once, and was rejected because I rushed through 
it and did a poor job, but I'm sure it's not that hard to get it. Also, 
they payrate for writers is decent enough, varying from 3 to 5 cents per
 written word, if your work is accepted. Furthermore, there is generally
 a lot of data entry work to do. You may find requests like "copy 
this and 
that
 into thegiven fields" and stuff like this. It isn't necessarily very 
well paid, but you can easily knock out a few bucks a day if you stick 
with it for, let's say, half an hour daily. If you're lucky, you may 
find some categorization work once in a while, which is easy and 
generally well-paid. There is no minimum payout; they will automatically
 transfer your earnings to your PayPal account every day.
Overall, I hope I’ve been helpful at least to some of you. Feel free to ask your questions if you have any. 
P.S.: I intend to make a post for each of those websites in the near future, detailing the whole "process", with tips&tricks, guides and much more.
