看一下它的t&c不就行了
the account balance on the last business day of the month is higher than the account balance on the last business day of the previous month.
我以前几年都是这么存的,次要是这个月我半途转出了一些钱,发现了这句话 :
Ensure your account balance is higher at the end of the month than the beginning; and
Keep your account balance above $0 at all times.
不知道是不是必需月末再都转回来。
不论怎么样,都是包管比上月末的余额多的,由于上月末这个账号余额是0.
