Two of the largest US exchanges, Gemini and Coinbase, have been offered over $100 million from Ripple, to get XRP listed on their platforms. The reason for refusal is that XRP is regulated by one company, thus it has characteristics of security token, and US regulators are pursuing a policy aimed at preventing the spread of securities. So, if XRP is identified as a security, the issue then will not be about inclusion, but the exclusion of the cryptocurrency from other trading platforms, and can also be fined.
