I have a question: is it legal for an auctioneer to auction themselves?

It's so hard to do this. These past few days, it usually takes several days to get a meager profit from the orders. I'm lacking patience and feeling restless. I open dozens of orders in a day and have no time for my own things. I've also signed up for the auctioneer exam and need to start preparing for it. I failed one subject last year and didn't pass, so I must succeed this year🏆
I hope everyone gets better and doesn't lose touch with their real life because of the crypto world~ Keep going!
