ResearchCoin (RSC) jumped 15% on its Coinbase listing, despite the exchange stating it is unaffiliated with the project, even with CEO Brian Armstrong's involvement. The listing is unusual given RSC's low trading volume and its previous presence on smaller, "tier 4" exchanges like CoinEx with only $17,117 in 24h volume. Investors should be cautious of potential volatility due to the atypical listing and the project's low liquidity profile.
