As the world becomes increasingly interconnected, does the traditional financial system, with its geographic and jurisdictional constraints, still hold sway? Or are we on the cusp of a new era, where the only limitations are the ones we impose upon ourselves, and the frontiers of finance are as vast and boundless as the digital universe itself?
