币界网报道:A weaker dollar, coupled with an increased appetite for risk among investors, could help boost Bitcoin again, LMAX Group strategist Joel Kruger said in a note. Bitcoin fell 1.7% amid trade uncertainty and concerns about tensions in the Middle East. The dollar index fell to a three-year low of 97.789. "A weaker dollar is generally good for cryptocurrencies, supporting a potential rebound in Bitcoin and Ethereum as investors move back into riskier assets."
