The main advantages of trading with HACHIJUNI include its strong regulatory backing from the FSA and its personalized customer service. The company also offers a wide range of products, including stocks, bonds, and investment trusts. As someone who appreciates face-to-face service, the personalized approach is a significant benefit. However, the higher trading fees, especially for face-to-face transactions, and the lack of international focus might be a limitation for those seeking a more cost-effective and globally accessible platform.
