I have a question on PoS and term deposit, for example I have 1000ROI, and I sign up 1 week term deposit. So, after 1 week, I will get 1000ROI + term deposit 2.12% + PoS 8%, is it correct?
Should be calculated this way.You have enough ROI,I suggest you partial deposit, time press 1,3,6... so that you can more flexible use
