A U.S. government default would trigger an initial pull-back from crypto currencies followed by a "push upward" the CEO of London-based crypto firm Blockchain.com said on Thursday. The U.S. government could fall behind on its bills next month - and even default on its debt - if Congress does not raise a $31.4 trillion cap on government borrowing, a failure that could trigger economic calamity and panic on global financial markets. "On a long horizon, these are probably good for crypto...If the U.S. government defaults, we'll probably see a quick pull-back and then a very strong push upward in the crypto market."
