Essentially a GPT site in app form but with its own integrated bitcoin wallet, ZBD has some other unique qualities like a close tie-up with assorted "bitcoin earner" game developers (primarily Fumb Games) and bots to exchange Bitcoin via Discord and Telegram
NATURE OF WORK AND PAYMENT
As mentioned at the outset, as far as earning goes, it's basically a GPT site with game and other offers, surveys and such. All activities pay out in SATs, directly to your ZBD wallet (a little more on that later). The "main thing" that's always accessible is the Daily Poll, which has you answer a question and then view a typical mobile video ad. You have to do that three days in a row and then you get a random amount of SATs up to 100.
Surveys are provided by something called Prime Survey, which I'm not sure if it is the same company as Prime Opinion (a major survey site that isn't always too popular with online side hustlers). Whatever the case, from skimming it here and there it seems to offer insulting pay, like 20 cents per five minutes or a whopping $2.40 per hour. Not even sure about survey quality or screenouts as I'm not even going in for that kind of money.
It has a fairly robust selection of games and offers of the usual GPT sort, but you always have to do the mental math of $1 equaling roughly 1000 SATs (give or take based on the current Bitcoin market). Some offers I've seen are competitive with the better "regular" GPT sites, some not so much, but you have to deal with the extra step of not just SAT payment but also dealing with the app's own unique Bitcoin wallet.
One last point of note is that this app has a unique and close relationship with developer Fumb Games, who have been pumping out about a dozen "earn bitcoin within the game" titles over the last few years. If you want to actually collect the SATs you earn from those games, you'll have to get ZBD's app going and set up their wallet.
SITE HISTORY / LEGITIMACY
The group behind ZBD is Zebedee LLC, founded in 2019. It's based in New Jersey and headed up by Simon Cowell (but not THAT one ... he must get really tired of this). While a fairly new company, it has some major investment money behind it including some big-name venture capital firms and Square Enix on the gaming end of things (though you don't see their presence at all in the app or ecosystem as of this writing).
INTERNATIONAL ACCESS
I'm not seeing a good list of countries available anywhere. The current Terms of Service only specify the US and EU. Search capture from an older version of the site suggests it might also be available in Brazil and the Philippines. Beyond that, I guess it's just check your local app store and see.
STARTING OUT
Download from one of the two big app stores and go. A KYC may be required to cash out eventually, but seemingly only for certain methods and conditions right now.
They also do have periodic "leaderboard tournaments" for bonus SATs and 2x reward periods and such you might want to keep an eye on. And there is a Friday "vibes party" on Discord at 4 PM EST that promises free SAT giveaways, though I haven't checked this out personally yet.
PROBLEMS WITH ZBD
I don't know if this is a universal issue, or was just temporary to several months ago, but at first I had one heck of a time getting this app to work. It just did not seem to care for any internet connection it was presented with; not even home wired, direct cable tethering to my phone, nothing was good enough for it! Eventually the app had an update after a couple months and started working for me all the sudden, and now it's not being fussy about even public WiFi connections. But after leaving it idle for a few weeks I did have to reinstall it to get it working again as it would just get stuck on its logo bootup screen forever. It can be very persnickety to run.
They recently listed some sort of web browser login option, at app.zbd.gg, but I've yet to be able to actually get that to work.
FINAL VERDICT - May Work For You
ZBD is a more ambitious project than usual for a GPT site, and it has some unique potential. It has its own wallet (that can further be accessed with extensions for most of the major browsers including Brave), it has little additional features like being able to add SAT tipping to Telegram and Discord channels (so long as all involved are using the wallet). And it has a pretty good referral program whereby you can earn 20% of a referral's earnings in their first year and 30% once you refer more than five (though you have to KYC first to unlock this). There's also the direct tie-ins with a whole slew of "bitcoin miner" games now.
They always seem to be working on it, and there's lots of room for growth (and it has real investment money behind it), so I think it's at least worth keeping around and keeping an eye on. But as of this writing, it just isn't a great earner. It has some OK GPT offers here and there, competitive with other big sites, but with the added hassle of getting money out of its unique ecosystem. The "bitcoin earner" games just don't tend to pay much, for example Bitcoin Miner now limiting you to withdrawing only about 33 cents per day from it. And there isn't really anything else of note going on, other than bad surveys and very tiny and limited rewards for watching video ads. If there's any big future I think it's the in-app SAT-earning games finding a way to offer more than they do now.
