New banking details

Dear Bitstamp clients,

We would like to inform you that Bitstamp now has new bank details, please check attached file.

We would like to assure those of you who sent deposits to our old details that our old IBAN is still active and your transfers, if otherwise sent with correct information, should arrive without a problem.

Please note that SEPA transfers usually take 1 to 3 business days to arrive and would kindly ask those waiting for your SEPA transfers longer than usually to please send us a transfer confirmation so that we can examine our bank account log and locate your transfers.

Also for those waiting on deposits we ask for your patience; we have accumulated a long list of transfers which lack information or contain wrong information which means we need to manually go through all of them instead of our system sorting them automatically.

Best regards
CEO, Nejc Kodrič
Bitstamp LIMITED
