Personally, I am not sure, I'm 60% convinced that XRP is a security since it is backed by a company (which could be profiting from it).
XRP is not to be even compared with Bitcoin in both limited supply and in security. As a newbie in the crypto space, don't consider Altcoins, Bitcoin is safe to invest if you know you don't want to loss money in Altcoins.
The OP does not refer "security" as it seems you define it.
The word security in finance, refers to something that can be traded and produce gains to a company (e.g, stocks).
