Assuming the current DJT price holds or goes higher, and the rate is 60% averaged for the month, it could be up to 2k per month or more. Then of course you have to pay pedojoe's cut too (fed tax).

But the monthly income depends both on the rate and the price of the stock, so if the price goes down (which is the entire point of short selling), then the income will be reduced, and eventually the rate will go down too.

Although the rate is more of an indicator of how hard it is to borrow the stock than the stock's actual price.
