X. Risk Disclosure

1. The Customer has acknowledged that (i) Plusplus does not have authorization from FINMA and is not subject to FINMA supervision, (ii) Plusplus exclusively processes transactions for customers to exchange customer funds into TOKEN, which do not qualify as securities or financial instruments under the Swiss Financial Services Act (FinSA) and relevant circulars of the Swiss Financial Market Supervisory Authority (FINMA), and (iii) the TOKEN are held available for the customer by Plusplus at all times and are transferred individually and technically segregated to a blockchain for this purpose (individual custody).

2. The Customer has further acknowledged that TOKEN can be very volatile and/or inflationary and that the underlying markets can be illiquid, with the risk that their value can decline significantly or that such TOKEN can even become completely worthless for other reasons such as regulatory or technical reasons. The Customer acknowledges and agrees that crypto assets are not guaranteed or secured by any particular nation, institution, company, person or by Plusplus. Furthermore, the Customer acknowledges and agrees that TOKEN are not regulated in some jurisdictions and their legal and regulatory status may be uncertain, so that Plusplus's SERVICES are subject to corresponding risks.

3. The Customer is aware that TOKEN, despite professional security precautions by Plusplus, are exposed to significant technical risks. In particular, there is little technical experience with some features of the SERVICES to date, which is why their stability, error-free operation, availability and security cannot be guaranteed. Security vulnerabilities or misconfigurations can be exploited by attackers, which can lead to the irrevocable total loss of the Customer's TOKEN. Even the most modern security standards offer no complete protection against targeted cyber attacks, zero-day exploits or internal errors. The Customer acknowledges that in the case of technical compromise or errors, all of the Customer's TOKEN may be irrevocably lost, without the possibility of reversal or recovery.

4. The Customer confirms that they have read and understood the corresponding product-specific risk disclosure information for the SERVICES concerning them, which are made available to them on the website.

5. The Customer fully acknowledges and accepts the risks associated with the SERVICES. The risks listed in the T&C and in the brochure mentioned in this section are not exhaustive. Plusplus excludes any liability to the extent permitted by law.

XI. Liability Exclusion

1. All SERVICES, including the information provided therein, are made available by Plusplus "as seen". Plusplus excludes any liability to the extent legally permissible and is only liable for intentional or grossly negligent acts. In any case, liability is limited to direct damages; the assertion of indirect or consequential damages, lost profits and defect-related consequential damages is expressly excluded.

2. The Customer acknowledges that the transactions to be carried out for them by Plusplus are executed without discretion and delays of several weeks may occur. Plusplus is not liable for damages, including consequential damages or lost profits, arising from transactions carried out late or at otherwise unfavorable times (including liquidation upon termination). The Customer further acknowledges that for the purpose of executing transactions, the Customer's funds or TOKEN are held in settlement accounts or settlement wallets of Plusplus and are not privileged under bankruptcy law at that time.

3. Plusplus is not liable for acts or omissions of partner companies.

4. Plusplus is not liable for delays, errors or failures caused by circumstances that have their cause outside the control of Plusplus, such as force majeure.

5. To the extent legally permissible, Plusplus excludes any liability for damages due to delayed or unexecuted processing of applications or the provision of information.

XII. Provided Information

1. The information about TOKEN provided by Plusplus is not intended for use in trading or in the sense of advice on financial, investment, tax, legal, accounting or other matters. Plusplus is neither an asset manager, investment or financial advisor nor a securities house. None of the SERVICES constitute investment advice or an offer, recommendation or solicitation by Plusplus to buy, sell or hold any security or financial product. Plusplus makes no representation and gives no assessment regarding the advisability or suitability of any investment.

2. None of the SERVICES constitute general or individual investment advice. The financial products or transactions to which certain SERVICES relate may not be suitable for the Customer's investment profile and investment objectives or expectations. It is the Customer's responsibility to determine whether the respective SERVICES are suitable based on their interests and risk tolerance. Plusplus is not liable for any damages arising from the transactions mentioned here. Plusplus does not recommend using the SERVICES provided as the sole basis for Customer decisions regarding the use of the SERVICES.

4. Plusplus expressly disclaims liability for the accuracy, appropriateness or completeness of any information provided and is not liable for errors, omissions or other defects in the information, for their delayed or interrupted provision or for actions taken in reliance on the information. Plusplus excludes, to the extent legally permissible, any liability for damages arising in connection with the use of information about TOKEN or other investments provided as part of its SERVICES.

XIII. Term and Termination of Use

1. Unless otherwise provided, the contractual relationship between the Customer and Plusplus is concluded for an indefinite period. For the use of SERVICES regarding rental deposits, the conditions according to the respective applicable special conditions in their respectively valid version, which are made available on the website, apply in particular.

3. Plusplus is authorized to restrict or terminate the contractual relationship or the use of the SERVICES at any time without giving reasons with immediate effect.

XIV. Entry into Force and Amendments to the T&C

These T&C enter into force immediately. Plusplus reserves the right to amend these T&C at any time. For all amendments, the updated T&C will be made available to the Customer by email, which shall be deemed approved by the Customer in the absence of objection within 30 days.

XV. Fees and Remuneration

1. Plusplus charges customers fees according to the currently valid price list, which can be accessed on the website.

3. Plusplus reserves the right to changes and adjustments to the fee regulations.

In this context, the Customer is aware that it cannot be excluded that remuneration may lead to conflicts of interest in individual cases.

XVI. Notifications and Communication

1. The Customer shall immediately notify Plusplus of all material facts for the business relationship (e.g. changes of name, address, residence, telephone number or email address). As soon as electronic documents and notifications from Plusplus are accessible to the Customer or have been sent by email, they shall be deemed delivered.

2. The Customer agrees that Plusplus may communicate with the Customer via any electronic channels (e.g. emails, apps, websites or telephone). Communication may be carried out directly by Plusplus and/or via partners and third-party providers and their respective communication channels.

XVII. Severability Clause

Should any provisions, conditions or regulations contained in these T&C or in related documents be found to be invalid or unenforceable to any extent, this shall not affect the validity or enforceability of the remaining provisions of these T&C or other documents. The same applies if the T&C or the document should not contain an essential provision. Instead of the invalid or unenforceable provision or to fill a contractual gap, that valid and enforceable provision shall apply which comes as close as possible to the economic intention of the parties that was pursued with the invalid, unenforceable provision or for which a regulation was missing.

XVIII. Choice of Law and Jurisdiction

1. All legal relationships between Plusplus and the Customer are subject to substantive Swiss law, excluding conflict of laws and international treaties.

2. The exclusive place of jurisdiction (subject to other mandatory jurisdictions) is the city of Zurich, Switzerland. However, Plusplus is entitled to assert its rights also at the Customer's domicile or before any other competent authority, whereby the above choice of law remains valid.
