THEHASH CHAIN does not technically serve the following countries: the Russian Federation and Crimea, the United States of America, Cuba, Iran, Iraq, North Korea, Sudan, Syria, Pakistan, Sudan and Kazakhstan. Verification for these countries is also not possible, so documents of users from these countries will not be accepted for verification.

The exchange of goods or products, real or virtual, as well as money or currencies, carries a significant risk. The prices of these may vary over time and because of the occurrence of different events. As a result of these price variations, the value of your assets can increase or decrease drastically at any time and without prior notice.

By using the Website, you assume, declare and guarantee to be aware that any commodity, whether virtual or not, is subject to significant changes in value, and may even end up with a value equal to zero. That said, there is an inherent risk of loss of money related to the purchase, sale or exchange of goods in the market, both real and virtual, and the same applies to Cryptocurrencies.

Furthermore, you declare and accept that the exchange of Cryptocurrencies may carry special risks, which may not necessarily apply to currencies, assets or products of free exchange.

Therefore, there is no federal reserve, central bank, government or other entity that protects their value, and they are reached exclusively under the balance between supply and demand.

Although it is not our mission or our intention to define exactly what a Cryptocurrency and its' generation system is, we can point out, in a few words, by taking as reference bitcoin and ethereum, which correspond to a global, decentralized and autonomous, self-regulated system, through which a virtual commodity, or digital asset, called Cryptocurrency is generated and circulated, and whose value is based on the trust the users themselves give the system.

In this regard, you declare to know and accept that the trade or exchange of Cryptocurrencies can be susceptible to irrational (or rational) bubbles, can be subject to loss of trust, and in consequence could lead to a collapse of your demand regarding the offer.

Merely by way of example, as the scenarios may vary, the trust in the Cryptocurrencies could collapse as a result of an unexpected change imposed by a software developer, of a prohibition imposed by some government or state, of the creation of a technically superior alternative, or simply of an inflationary or deflationary spiral.

What is more, the trust in Cryptocurrencies could collapse due to possible technical problems, such as when the money of the owners or people who interact or operate with Cryptocurrencies were stolen or lost, or if hackers or governments cause the prevention of transactions being made.

As for the transactions of purchase and sale of Cryptocurrencies, you understand and accept that once the orders are entered into the Platform and they are processed as completed or pending, it is not possible to cancel, reverse or change those orders. Each User is responsible for maintaining an adequate balance of funds /cryptocurrencies in order to avoid situations in which the costs associated with the withdrawal of the Cryptocurrencies or legal tender are greater than the net amount of said withdrawal. Furthermore, Users will be responsible for the information provided for any subscription or withdrawal in Cryptocurrencies to or from their hash-ex.com Account to or from an external Cryptocurrency wallet. Therefore, if the information provided by the User to carry out such shipments or receipts of Cryptocurrencies to or from wallets of hash-ex.com is incorrect or does not correspond to the particular type of Cryptocurrency that is being sent or received, you accept that the prior could mean the total loss of those cryptocurrencies sent or received.

hash-ex.com reserves the right to refuse to process any purchase, sale or withdrawal order of Cryptocurrencies or legal tender, in its sole discretion, if hash-ex.com suspects that the order involves (or has a high risk of involving) activities related to money laundering, terrorist financing, fraud, or any type of financial crime, or activity that is not in accordance with the rules of these Terms and Conditions; or in case of being required judicially or administratively to do so by some competent authority. In such circumstances, hash-ex.com will cancel or refuse to process the order, without an obligation to allow a subsequent order at the same price or on the same terms as the order canceled or refused.

Finally, it is necessary to point out that there might be other possible risks not considered or identified in these Terms of Use, which Registered Users are willing to bear, freeing switch.com from any responsibility for them. Therefore it is crucial that you carefully analyze your financial situation and your risk tolerance before buying or selling Cryptocurrencies on the Website.

hash-ex.com does not control or have any interference in the base protocols that regulate the operation of the Cryptocurrencies supported by the Website (the "Protocols"). Therefore, hash-ex.com will not be responsible for the functioning of the Protocols, nor does it guarantee its operation, security or availability. Therefore, you declare to be aware that the Protocols may be subject to modifications to their rules of operation (“Forks”) and that such modifications may materially affect the value, utility and availability of the Cryptocurrency, of which protocol is modified. Consequently, if a Fork occurs, which affects any of the Cryptocurrencies supported by the Platform, you agree that hash-ex.com may temporarily suspend any operation linked to it (with or without prior notice) and that hash-ex.com may, at its sole discretion, decide to operate (or cease to operate) the underlying cryptocurrency that the protocol modified through Fork. You acknowledge and agree thathash-ex.com will nottake any responsibility for any damage caused by a Fork not supported by the Platform.

In case that switch.com pronounces itself negatively about an eventual Fork to one of the supported Protocols, or does not pronounce its position regarding it, and a User wishes to participate in the results of that Fork, the User must withdraw the Cryptocurrencies connected to the affected Protocol from his hash-ex.com Account to a wallet that supports the Fork before the budgeted date for that Fork.

If a Registered User uses his Account to manage transactions for the benefit of third parties other than the User who owns the Account, or operates his Account with funds owned by third parties, without the corresponding prior authorization of switch.com.

Furthermore, switch.com expressly reserves the right to cancel and /or close Accounts, which have not been successfully verified ("Accounts Not Verified" or "Accounts Disabled"). After making reasonable efforts to verify and find the holder of the respective Account for at least 6 months, and without having achieved the objective, switch.com may donate the goods (CLP, USD, EUR, RUB , Cryptocurrencies, or others) that have been left in the Unverified Account to any NGO, group or association for Cryptocurrencies, without any further responsibility for switch.com, and against which you agree not to take any action by accepting these Terms of Use.

The suspension or closure of an Account will not affect the payment of service charges accrued and due for past transactions. At the closing of an Account, Registered Users must submit a valid bank account of their ownership so that switch.com can make the deposit of any amount that it may owe to the said Registered User. The Registered User must be the owner of the bank account, otherwise switch.com may refrain from making the payment online and in that case the User must contact switch.com as indicated in the "Contact" section below.

Any balance in Cryptocurrencies can only be transferred to a bank account once converted to a currency that is acceptable by the respective bank, as long as the Cryptocurrency balance is sufficient to cover the transaction costs (commission of switch.com and network fee) and the possible costs of the subsequent transfer.

hash-ex.com will transfer the amount due as soon as the Registered User requests it and within the deadlines specified by switch.com for these purposes. However, after 6 months without having provided a valid bank account or without having contacted hash-ex.com, so that it may have made the payment, and after hash-ex.com having made reasonable efforts to contact and return the said money to the Registered User within that period, switch.com will be exempt from paying the debt and therefore you will not be able to recover the said money.

In the case of closing an Account, if the costs of restitution of any amount due to the User are greater than the amount due, you agree that no refund will be made. In the event of a possible suspension, closing or disabling of a Registered User, all pending operations will be carried out or executed and in no case will the charges or payments that the disabled Registered User have made to Switch be returned or reimbursed for any reason.

Furthermore, in case of canceling or blocking a previously accepted Account, for any reason, switch.com will inform or notify you of this decision, except in the case of a requirement or instruction of the contrary made by any governmental or state institution or other authority, if it conforms to the respective legal and or procedural rules that are applicable.
