In addition to our already live futures contract (ARBUSDTM23), BitMEX users will soon be able to trade ARB with up to 50x leverage via two new listings – ARBUSD and ARBUSDT. ARBUSD Quanto Contract SpecsAs with all quanto contracts, the ARBUSD product has a fixed Bitcoin multiplier, regardless of the ARB/USD price. This allows traders to long or short the ARB/USD exchange rate without ever touching ARB or USD. Traders can post margin in XBT, and earn or lose in XBT as the ARB/USD rate changes. This allows users to gain exposure to the price of the ARB token and trade it with leverage, without needing to have ARB holdings.
