What must be in the ToS of an exchanger?

There are many signs by which you can distinguish a high-quality exchanger from a low-quality one. One of them (and BestChange also pays attention to it when adding to the listing) is proper Terms of Service. The link to them must be visible and the very document must contain the following information:
✅ Conditions which must be met for creating an order.
✅ Conditions on which the rate is fixed. For example, 30 minutes after the creation of the order. Or not fixing at all but being calculated at the time of payment.
✅ Maximal time for paying for the order by the client.
✅ Ways of informative support to the client after they pay for the order.
✅ Ways of solving the problems connected with blocking the operations or of the accounts by the bank, entering wrong details etc.
✅ Privacy policy — how the data entered by the client is stored and used.
Of course, terms of service are not the only sign that the exchanger is legit. But with other criteria, it is also important, as it allows you to clearly understand whether you are satisfied with the conditions sent by a particular service and are there any pitfalls.
