The whole thing is absurd because we don't have to guess or speculate-- just look at what the actual historical rates have been for BTC margin loans on exchanges such as Poloniex. Nowadays the rate is pretty low, 3.5% to 5%, but it can spike to much higher levels based on supply and demand (for example, leading into the bitcoin gold fork, rates spiked because the exchange wouldn't credit BTC balances with the fork if the coins were being lent at the time).
