This looks half-baked. There's no proof that they have any "brands you love" on the platform and their apps aren't available in the app stores.
Their payouts look unreasonably high, with cash back rewards up to 40%. Big red flag.
It would be much more believable if they were using something like BTC over Lightning for payments. Getting traction with a native token will be very difficult for this type of app.
Their social media following is also very low.
