3.4. Trading Restrictions: HBL reserves the right, at its reasonable discretion, to impose, amend, or remove restrictions, parameters, or limits applicable to any transaction or Client of Brokerage Services. These measures may include but are not limited to: (i) controls over maximum Request sizes; (ii) limits on HBL's total exposure to Client; (iii) filters against duplicative or clearly erroneous Requests and/or Brokerage Transactions; or (iv) any other controls required by applicable regulations or HBL's internal policies and procedures. Furthermore, HBL may only offer certain Virtual Assets under Brokerage Services exclusively to Professional Investors. Such trading restrictions may delay, prevent, or modify the submission and execution of Requests, including the decision by HBL not to respond to and/or confirm certain Requests. The Client acknowledges and agrees to adhere to these restrictions and to assume responsibility for any Request and/or Brokerage Transaction that breaches these constraints or exceeds established limits. HBL retains the right to withhold response or confirmation to any Request, even if it falls within the established parameters. Any changes to these restrictions will be communicated to the Client in a timely manner, where practicable.
