In the Binance Web3 wallet, brushing #Alpha, both buying and selling are definitely counted towards the trading volume, except for the last sale back to U which is not counted; everything else is included.

This is equivalent to double trading volume on BSC, with coins and coins (ZKJ and B2 trading pair) also doubled, reducing wear and interactions. Previously, brushing 16384U corresponded to 14 points of wear, now it can be 32768U, corresponding to 15 points, plus balance points 2 points (bulk brushing, the best amount is 1100U, per account), accumulating 17 points, 17*15=255 points, basically satisfying all airdrops.
