Even with understanding how to use it,you still won't be able,cuz staking is understandable but there is no way to do it from your account - you will encounter the same issue as per withdrawing, only possible way is to register a new account with custom(very large) CPU stacking,deposit inside enough EOS to delegate CPU stacking to main account. There is no calculator/real numbers/information how much EOS you need to stake in order to withdraw your current balance.Goodbye and FU EOS!
