The advantage of what that employee was talking about was that, when receiving payments from customers, the member establishments of the bank's accredited network would not have to pay fees beyond those 400 crystals.
That is, of course, considering that the establishment would do all its operations through the array of its establishment.
In other words, by receiving the crystals directly into their account through such array in their establishment, i.e., without going to the bank, that account holder would not have to pay any fees for receiving them, regardless of the amounts!
That was obviously not advantageous for ordinary citizens who had no business. After all, such people could make transactions between accounts of up to 9,999 crystals without paying fees.
But for business owners who were perhaps going to make dozens, hundreds of sales a day, this was worthwhile.
