I never heard about nobi before - is it a wallet or something? The project is similar to Chinese or Asian. KYC registration is unanonymous crypto?
From their app, it says it offers like bank services. So it is like your crypto bank account.
But reading some of the reviews, some are saying the fees are too high. And remember, you need to submit KYC. If it is okay with you to submit your KYC docs, then that's fine. And from their current promo, you can only get the pool prize if you win. Your choice if you want to submit or not your entry.
