Ripple’s XRP (XRP) is not a security because it does not fit the definition of an “investment contract,” the “only” legislative definition that it could “possibly” fit, according to Jeremy Hogan, a partner at the law firm of Hogan & Hogan.
In a series of tweets on April 9, Hogan explained that, in his opinion, XRP could only be considered a security under the definition of an "investment contract," as it doesn't fit the other definitions of a security such as stocks or bonds.
