Tesla’s terms and conditions also caution that customers need to be careful when inputting both the bitcoin address and amount to be paid. It notes in all caps that “bitcoin transactions cannot be reversed” and “if you input the bitcoin address incorrectly, your bitcoin may be irretrievably lost or destroyed.” Customers are also responsible for directly paying all bitcoin transaction fees associated with their purchase, and Tesla warns that although bitcoin payments typically take less than an hour to complete, this can extend to up to “one day or more.” And because of bitcoin volatility, Tesla warns that the value of any refund made in bitcoin “might be significantly less” than the value of bitcoin relative to US dollars at the time of purchase.
