The US-based cryptocurrency holding Coinbase has indirectly refuted rumours about possible listing of Ripple on Coinbase and GDAX. The rate of the coin, which earlier jumped by 20%, dropped again below $1.

The Ripple payment system token jumped from $0.9 to $1.08 within a day. Several factors contributed to the growth of its rate. First, one of the largest South Korean banks, Woori Bank, entered into a partnership with Ripple to test cross-border payment system using distributed registry technology.

Secondly, there were rumours that the consortium of Japanese banks successfully completed testing of the Ripple-based payment system for interbank and international transactions. The consortium consists of 30% of Japan's commercial banks, including such large financial and credit organizations as AEON Bank, Nomura Trust and Banking, Resona Bank and Mizuho.

And the last, but not the least factor, which pushed the Ripple rate up, was a rumour that the US-based crypto-exchange Coinbase will list Ripple.

But after a few hours after the rumour began to spread over the community Coinbase refuted this information:

The price of Ripple fell again to $0.98.
