In accordance with regulations, we may ask you to present proof of the source of funds during the sale process. Therefore you need to have a valid proof of the origin of your Bitcoin from the place where you bought or acquired it, such as a receipt or confirmation of purchase. This only concerns Bitcoin which has not been bought directly from Safello.
If you have been requested to prove the source of funds and fail to do so, your transaction will be declined.
Please be so kind as to get in contact with our support if you would have any specific questions about which documents we could potentially approve in your particular case before placing an order.
