Today alpha刷koge, bought and sold 16 times each, took 18 minutes, and incurred a loss of 1.6465U. I've been doing this for a week, and the loss has been around 1.6U each day, except for yesterday when the loss was lower. However, I still can't figure out the reason; it might be because yesterday's刷 coincided with a rise in coin prices? Or I will try starting the刷 around 10:40 again to see if there's any relation to the time.
