The market for BUX tokens is relatively illiquid. This means that the volume of BUX tokens being traded is relatively small. Therefore, we apply a maximum of 5000 BUX for one single trade. In this way we protect you from too much slippage (the difference between the expected price of a trade and the price at which the trade is executed). In other words: with the maximum order of 5000 BUX we protect you to pay a price that could potentially differ much with the price you expected.
