ZCash listed on Coinbase

Yesterday while purchasing some BAT on Coinbase I noticed that ZCash was now available for purchase.  That makes Coinbase 3 for 5 on the 5 assets that they were considering listing.  Since the addition of 0x in October, Basic Attention Token and now ZEC have been added in relatively rapid succession compared to listings of years past.  A reasonable assumption might be that Lumens (XLM) and Cardano (ADA) listings are right around the corner.
