Have $400 or more during a single run
Hold $400 or more at once during a run. Interest caps at $5/round (from $25 held), so to reach 400 you lean on money Jokers (Bull, To the Moon, Rocket, Golden Joker and friends) and hoard rather than spend. Build an economy engine and sit on your cash until it crosses 400.
