FOFB (Fund of Fund BlockBank) is the first blockchain-based fund-of-funds digital currency investment system, with FOFbit (abbreviated: FOFB), the intrinsic value transfer token supporting the FOFchain ecosystem. Holding a single digital asset carries extremely high risk; by converting it into FOFBit, its market value is merged into the total value of quality assets in the mother fund, effortlessly upgrading to a portfolio of FOF assets. When redeeming assets, you automatically receive the corresponding proportion of the total market value of the mother funds asset reserves on the chain, and it is automatically converted into any digital asset for withdrawal.
