I have been doing surveys for a decent living for over 5 years and there are LOT of things you're missing in your "method". Specially for those not living in the U.S. or U.K.
1. Since the biggest and only profitable survey opportunities come mostly from the U.S. and U.K. your identity must reflect everything about either one of these. Therefore if you do not live in any of these countries, you have to get yourself a reliable proxy/vps/vpn to cheat the system. Problem is, over the years, these survey panels' security measures have become more and more sofisticated, to the point only residential proxies/vpn's will work and sometimes only a few providers will, residential ip's are NOT cheap (can go from $30 to 50% /mo, so if you're making good money with surveys grinding for hours and hours everyday, you'll end up on negative numbers)
2. Now most survey panels require you to "verify" your account before you're able to withdraw, verification methods are getting more and more strict now, one of the most common ones is Phone verification. Phone verifications are now being monitored so that if the number you verified your account with does not belong to the state you indicated you live at, bye bye account. Some other panels even request your government ID to pass the verification, good luck with that! In brief, verification is a bitch now.
3. With surveys, there's really not such a thing as a fixed amount of money per hour you can make, not even a range of income per hour. Things such as survey availability, ability to qualify, surveys crashing and bugging in the middle of completing them (and therefore not getting credit for it), or even fully completing the survery and still NOT getting credit for it at the end, are very common issues in this "business" and they can drastically alter the amount of money you can make, it's never stable.
4. As for withdrawal methods, the vast majority of panels pay via PayPal, and that's another issue, if you do not have a VERIFIED, U.S. or U.K. account, you can't just use your foreign country PayPal account to cash out as most panels can already detect this and you're essentially fuk'd if you do. So you have to create a U.S. / U.K. account under your fake ID and verify it. Only problem is, Paypal is now also requesting your government ID. to fully verify your account, so again, good luck with that!. Now probably the second most used withdraw method is Amazon/Walmart/Target Gift Cards, problem with that is your have to sell them to 3rd party buyers for real money but losing 25% of it's value at best, not a very profitable method if you ask me. What else is left? Visa prepaid cards? only way to get the money off of them is to link them to a paypal account and withdraw the money to yet another paypal account, okay? I actually do that, paypal takes a cut but better than nothing I guess.
5. Qualifying for most of the high paid surveys ($3 or higher) is literally impossible because those are surveys targeted for professionals on an specific field ONLY. if you do not have serious knowledge and experience on the specific profession and field the survey requests, you're just not qualifying, ever, period.
So all in all, if you do not belong to any of these 2 countries, please don't bother, it's just too hard to make any money with surveys anymore.
