* About this Project: A new meme coin birthed by fans of the XRP community. Ripple Inu is Hyper-deflationary with an
                      automatic 2% Reflection and 2% Burn system. One of Ripple Inu's key utility is the building of a thriving,
                      supportive and engaging community that spreads the awareness of XRP, creating that ripple effect.
