Fixed investment is to agree on the time and amount with the bank, and then the bank will deduct the corresponding amount from the account to subscribe for the fund when it expires. If the current balance is insufficient, the bank will continue to subscribe for the fund next month, but it will not make up the previous balance. That is to say, if the balance is insufficient for three consecutive months, the bank will automatically cancel the fixed investment business.

Generally speaking, there will be a minimum starting investment, 100 is the lowest, but some foundations set 200 as the minimum amount. Note that 300 is definitely enough for the minimum starting pitch.

You don't need to deposit 1000 first, as long as you deposit enough balance before maturity.
