If the proposal to permanently halt migration from developing nations actually goes through, it might rank among the most spectacular self-sabotage moves in recent American history.

This would be fantastic news for competing economies—especially those that have traditionally struggled to match America's magnetic pull on the planet's most ambitious and driven talent. For decades, the U.S. dominated the global race for human capital, scooping up engineers, researchers, entrepreneurs from every corner of the world. That competitive edge? Built on keeping doors open.

Closing those doors doesn't just block opportunity—it redirects the flow. Other regions stand ready to welcome exactly the kind of relentless, innovative minds that built Silicon Valley, Wall Street, and yes, the emerging blockchain ecosystem. When one gate shuts, another swings wide open.
