Coinbase explained in its blog post that Coinbase Pro would start accepting DASH deposits on Monday (September 16). This will continue for at least 12 hours before full trading becomes available. The earliest time that trading will begin is 00:00 UTC on Tuesday (September 17), assuming that there is sufficient liquidity.
Two trading pairs are going to be supported: DASH/USD and DASH/BTC.
As is usually the case, trading in the new order books will start in phases, "beginning with post-only mode and proceeding to full trading should our metrics for a healthy market be met."
DASH will be supported in all of the jurisdictions where Coinbase Pro is available with the exception of New York state and the United Kingdom.
Coinbase has this to say about Dash:
Created in 2014, Dash is a cryptocurrency optimized for payments that has optional speed and privacy features. At this time, Coinbase will not support these features. Dash is accepted at over 4,000 merchants worldwide. Its unique network architecture consists of both regular miners and privileged machines called Masternodes. Through its off-chain community governance system, anyone can submit and vote on proposals to improve the ecosystem’s functionality, utility, and adoption.
Initially, DASH will not be available on Coinbase Consumer (Coinbase.com) or in Coinbase's mobile app (for iOS and Android), but once DASH support has proved to be stable on Coinbase Pro, it is likely to get to these other two platforms.
According to CryptoCompare, at press time (05:16 UTC), DASH is trading at $85.49, up almost 4% in the past 24-hour period:
