/*

Welcome to the revolution of XPS6900 (XPS), a meme coin that turns the tables on traditional finance with a bold, satirical twist! 
XPS6900 is the audacious counterpart to the S&P 500-inspired SPX6900. 
While others chase bigger numbers, XPS6900 embraces the power of reversal—because sometimes, flipping the script is the ultimate move.
