Scarlet-Clicks,
is a typical PTC website, where you can earn money from viewing ads.
Though, they have other ways to earn money from, like ScarletGrid, PTC
Wall and PTSU it remains a "Bux type model". Their programs are similar
to, doing tasks, answering surveys and clicking ads. The PTSU is a Paid
To Sign Up program, where you will be paid after signing up to another
program they're promoting.
They have been in this business for more than 6 years and never had an issue paying their members.
Scarlet-Clicks doesn't promise that you will get rich if you will join
them, but they will surely give you an opportunity to earn extra cash
without spending a dime. However, you will only see their full potential
if you can get plenty of DRs and upgrade your membership.
