Disclaimer Crypto assets are not legal tender and may be used to settle a payment only if the person receiving the payment agrees. The price of crypto assets may fluctuate due to changes in the balance of supply and demand and other factors, which may result in losses. Fees and other charges may apply to crypto asset and related transactions. For details on fees and other charges, see “Fees and Taxes” on our website. To engage in over-the-counter crypto asset derivative transactions, you must provide a margin deposit. For details on the required margin deposit, its calculation method, the applicable margin rate, and other margin-related information, see “What is bitFlyer Crypto CFD?” on our website. Over-the-counter crypto asset derivative transactions let you trade amounts exceeding your margin deposit with a small amount of funds. However, rapid price fluctuations of crypto assets and other factors may cause losses exceeding your margin deposit within a short period. In over-the-counter crypto asset derivative transactions, factors such as sudden price movements or the execution of a loss-cut may result in a trade being executed at a price or under conditions different from those you anticipated at the time of your order, or may result in a trade not being executed at all.
