Transfers in Bitcoin system may permanent in the status of “Unconfirmed Transaction” for a long time. Most often this happens due to the fact that one of the operations does not process. According to the rules of Bitcoin network such a problematic transfer is attached to another block and then is processed by standard procedure. If this does not happen, the funds are returned to the sender within 1-7 days. Unfortunately, our exchange service cannot affect the processing speed of such transfers. After being deposited or returned to the sender the situation with the application will be resolved by its completion or cancellation with the return of all monetary obligations of each party if such payment is delayed for a rather long period of time. The decision is taken towards each case separately.
