In America, largest pack of SQ is 86 paid SQ, 81 free SQ. 167 SQ in total. This pack is $80 (not counting additional taxes and other fees)
8600/167 is approximately 51.50, which is the number of packs he would have purchased to get 8600 SQ.
51.50 x 80 = $4,120.
Our boy here lost at least $4k in this match against Artoria, and she said that's what he lost TODAY. He's either deep in debt or rolling in cash, because that implies he's lost more SQ than this.
@Cadavrus If you put it another way, that’s the amount of cash you’d need to have 12 hours sex session with Bunny King. Though from the dialogue it seems that she has him pay in that way on purpose
