The fixed investment fund is not a savings deposit, so there is no problem of automatically transferring it to the account with interest when it expires. Fixed investment funds can be redeemed at any time, but it is better to redeem them when there is a certain income. Fixed investment fund is a voluntary behavior, which can terminate fixed investment at any time and redeem all or part of the fund shares. After the fund is redeemed, the account is empty and will not be cancelled. When you want to invest in a fund, you can invest at any time, which is very convenient. There is no charge for empty cards. It usually takes 7 days for redemption funds to arrive.
