Yep, exactly. The value of your CUB must equal the value of the BUSD. Since CUB decreased in value w.r.t BUSD, it needed to sell BUSD to buy CUB to balance it out.

And I hope we're at the bottom now ... considering whether I should buy more CUB now, but I've been doing this the whole way down ... trying to catch a falling knife 🤦‍♂️
