Doing Money Madness doesn't necessarily give attack EXP, but the requisite quests do give attack EXP--enough to get you to 61 if you didn't already do them.
To clarify - MM will only give attack, def, strength and hp exp if you speak with Daero. You do not need to speak to him to finish the quest, in fact you must finish the quest before you can be rewarded the exp.
