CoinMeta data: Senior researcher Tim Sun from HashKey Group indicates that the threat to Bitcoin comes from a possible second Fed interest rate hike, rather than the market transparency bill that failed to pass in the Senate. He points out that Bitcoin's trend now depends more on the financial situation and investment flows in the United States, rather than a stagnant market structure bill. Sun believes that the interest rate hike in October could lead investors to see September's hike as the beginning of a continuous tightening, rather than a single preventive measure, which might end Bitcoin's current upward momentum.
