PTC: Bux VS Aurora

As those who involved in PTC,
you will know that there is some different PTC script,
three most famous and wide-use script is Bux script (included of Bux-clone, YourOwnBux, Securebux), Aurora and Cash-Crusader.
Sample of Bux script: Bux.to, IsabelMarco, Earn3, Extra10
Sample of Aurora script: TheClickers, Cash-Harvest, ProwlingPanther
Sample of Cash-Crusader script: PersianPTC, AriaPTC

Bux script might be the favorite by most PTC earner,
especially newbie and investor,
as it can earn more money easily.
Most Bux script similar to HYIP,
where you can earn much money when you're invest.
In Bux site, you can purchase membership and referrals to earn easy money.

Besides, most Bux site use money-cycle model,
which they not earn through advertising (although they are advertising site),
but they earn from referrals and membership purchase.
You can see this clearly at most of the Bux site,
which they have unsustainable advertising price,
and 99% of their ads is self-sponsored.
[Example, 1000 ads view cost $10,
while member can earn $10 from clicking and $10 from referrals click,
where the owner will lost $10 through each ads purchase]

With those reason,
95% of Bux site cannot stand for more than 6 months.
Most of them will down, close, or holding payment (Bux.to) up to many months.
The reason they hold the payment is,
they have to wait for another money cycle,
which other people purchase anything in the site,
so that they can pay you.

Aurora script,
can said to be one of the best script in PTC,
which have slow-earning scheme.
Most Aurora script offer less than 1 cent per click,
and most have 4 level of ads,
which might be (1,0.75,0.5,0.25)in cent, (1,0.5,0.25,0.1)in cent, (0.5,0.3,0.2,0.1)in cent per click.
Some Aurora site even give $0.00001 per click,
which cause most member don't want to join.

Beside,
most Aurora script have lower referrals bonus rate too.
99% of Aurora site have less than 100% of referrals bonus,
which most of them only give 50% for normal member.

Another earning problem in Aurora site is,
if you purchase referrals,
you have very high chance to get inactive referrals,
since Aurora site member active rate is much more lower than Bux site.

The benefit for joining Aurora site is,
they are very stable.
Most Aurora site can stand for year easily,
since they have lower advertising rate which most advertiser like to buy ads at there.
An easy theory, who will buy 1000 visits for $10 or $20,
while they can have it for even lower than $1?
You might have very slow earning in Aurora site,
you can very sure that your money won't lose easily for site closing, admin run away,
or taking any similar risk just like in Bux site.

My final advice,
you can earn easy and fast money in Bux site,
you might also lost all money very fast in Bux;
Aurora might have lower earning rate,
but the risk is lower too.
Invest any site AT YOUR OWN RISK!
