作为一个实施例，不限制所述用户的所有可用交易记录与所述交易记录理论限度之间的数量关系。As an example, the quantitative relationship between all available transaction records of the user and the theoretical limit of the transaction records is not limited.

作为一个实施例，所述用户的所有可用交易记录与所述交易记录理论限度之间也可以存在数量关系，例如：所述用户的所有可用交易记录的数量大于等于所述交易记录理论限度的两倍。As an embodiment, there may also be a quantitative relationship between all available transaction records of the user and the theoretical limit of the transaction records. For example, the number of all available transaction records of the user is greater than or equal to two of the theoretical limits of the transaction records. Times.
