“30% Baby!”
indeed ... but regardless of the number, ANY claim to pay ANY amount of “interest” on crypto is fraudulent on the surface because crypto is a virtual entity without inherent value AND inherently offers no yield ... any “interest” exchanges may claim to pay boils down to them gambling in one fashion or another that crypto prices will go up up up ... so when crypto prices go down down down like they did in 2022, these outfits lose their bets and go tits up and customer “deposits” go poof ...
30% is the standard lawyer cha-ching.
