When i would read that then i would read it as "maximum payout" but as a maximum that comes into play when the house is bigger than 2000 Bitcoins at 1 x kelly. So that even when 1 kelly would be more than 20 Bitcoins the max payout would be restricted to 20 Bitcoins. I would not get the idea that, lets say 100 Bitcoins total in the house could overwrite max kelly and 20 Bitcoins could be taken in one bet. That would simply be too dangerous and the wording would let me never get the idea that it overrides the max kelly in this direction and not in the other one.
