We are pleased to announce that our company has received the high honor of being ranked No. 1 overall for the third consecutive year in the "2026 Oricon Customer Satisfaction® Survey for Cryptocurrency Exchange Spot Trading."

Furthermore, as a part of our commitment, we primarily offer trading via an **order book**, and all listed assets are available for spot trading on the order book.

Encouraged by this evaluation, we will continue to strive to provide services that our customers can use with peace of mind, aiming to create an even more comfortable trading environment.

We look forward to your continued support of bitbank.

* BIMI (Brand Indicators for Message Identification) is a system that displays a brand logo and an authenticated badge (blue checkmark) on official emails. By complying with the email authentication protocol (DMARC) and supporting BIMI, a company's brand logo and authenticated badge are displayed, allowing recipients to see at a glance that the email is not a fraudulent spoof. These security measures enable customers to open emails from our company with confidence.

** This refers to order book trading, which involves matching transactions between customers. As it is a customer-to-customer matching system, it generally offers the highest price transparency and allows for trading under the most favorable conditions for the customer.
