REQ was listed on Coinbase on October 12th, 2017.
This date is significant for a few reasons. First, it was the first time that REQ was available to trade on a major cryptocurrency exchange.
NOTE: Warning: Coinbase does not guarantee the listing of any particular cryptocurrency, including REQ. Coinbase reserves the right to list a cryptocurrency or delist a cryptocurrency for any reason at any time, without prior notice. Investing in cryptocurrencies involves significant risk and caution should be exercised when considering buying, selling, or trading in any digital asset.
Second, it was just a few weeks after the launch of the REQ token sale, which took place on September 15th.
The listing on Coinbase gave REQ a lot of visibility and liquidity, which helped to drive up the price of the token. Since then, REQ has continued to be one of the top-performing tokens in the Ethereum ecosystem.
