Hello, The reason that people don't take the 20%/year arb is that they are taking arbs that pay more than 20%/year. An additional reason, at some venues, is that the venue does not allow you to use 1 BTC to fully collateralize 1 short BTC future. At those venues, if you do this trade and the price of BTC goes up, you begin to pay interest to borrow dollars for your paper loss on the futures half of the trade. Edit: for CME in particular, I don't know, but I sort of expect that you cannot post collateral in crypto. |
