[Wintermute: Retail Investors Selling BTC to Rotate into Altcoins] According to a report by Wintermute OTC Trading on September 29, as reported by Jinse Finance, retail clients sold Bitcoin last week to fund a rotation into altcoins, a typical late-bull-market behavior involving profit-taking and migration to high-beta assets. The institution stated that market breadth has expanded to a level where, historically, the subsequent weeks saw a 'flat or downward' trend over 80% of the time (excluding early-cycle periods). They expressed hope that Bitcoin would continue its upward trajectory to generate new wealth to fuel further rotations. The report also identified oil prices, interest rates, and another Federal Reserve rate hike as the primary external threats to the current system.
