Former U.S. Secretary of State Hilary Clinton takes aim at the rise of cryptocurrencies, warning its potential to eventually destabilize nations, she said via video at the Bloomberg New Economy Forum on Friday. "One more area that I hope nation-states start paying greater attention to is the rise of cryptocurrency -- because what looks like a very interesting and somewhat exotic effort to literally mine new coins in order to trade with them has the potential for undermining currencies, for undermining the role of the dollar as the reserve currency, for destabilizing nations, perhaps starting with small ones but going much larger," the former Democratic presidential candidate told Bloomberg. Speaking of crypto, Bitcoin (BTC-USD) continues trading below $60K key level as China continues to clamps down on the space, now changing hands at $57.8K per token. Earlier, MicroStrategy CEO Michael Saylor said his company will continue to stack Bitcoin forever.
