Announcing The ETHUSD Quanto Futures Contract

We are launching an ETHUSD quanto futures contract with up to 50x leverage on 5 May 2020 at 04:00 UTC.

The first contract (ETHUSDM20) will expire in June. This new product will be the only one of its kind available in the market, and represents significant new trading opportunities on BitMEX.

ETHUSD quanto futures have a fixed Bitcoin multiplier regardless of the USD Ethereum price. This allows traders to long or short the ETH/USD exchange rate without ever touching either ETH or USD! Traders post margin in XBT, and earn or lose Bitcoin as the ETH/USD rate changes.

This contract combines the quanto feature of our ETHUSD perpetual swap with the expiry and settlement found in traditional futures. As with every BitMEX altcoin future, it expires quarterly.

Please see our blog for more information: https://blog.bitmex.com/announcing-the-ethusd-quanto-futures-contract/

What Does the Halving Mean For BitMEX Users?

The world seems like a very different place since the eve of the last Bitcoin halving in June 2016 – not least as the price of a coin was around $650 back then. And despite Bitcoin's relative infancy, as in life, so much has changed yet so much remains the same. Just like ahead of the halvings in 2012 and 2016, we're seeing the same questions. Will miners exit? Will the hashrate drop? Will confidence decline? Will there be a price correction? And today, all are with the added and swirling complexity of COVID-19.
