I recommend readers to calculate the potential profit themselves. I have been market making pretty much alone (if I do not count in those who were doing it manually) for almost a year on multiple pairs and did not really earn a fortune by it. I guess a lot of people will now try this mm feature and of course... the more market makers are there, the less potential profit is there to make (smaller spread, more competition). If many people start using this service, volatility will make much more influence on your investment than the market making itself. But good luck to everyone. I am looking forward to see how the volume reacts to smaller spread and how it affects my own market making activities. :D
