Second Account, definitely able to receive funds but if your second account is unverified, the funds will stay there and you cannot send it to anyone, including yourself. You can only use it to buy load and/or pay legitimate/partner stores' QR.
On the other hand, you can apply it for verification and surely will be verified (assuming that your requirements are good to go). However, your wallet limit may possibly become shared (but for some instance, it is not. Not sure if this is related on what ID you used for KYC/verification because I have few accounts, 2 of them are shared, other 1 is solo, and the other 1 is also solo). Advantage of having multis, is if you are the kind of person who cash-ins more than 8000 within a month via Cash-in partners like Pay2Go (even if your accounts are shared limit), you won't be suffering from having a 2%(?) deduction because you reached the max limit of cash-in via partners.
