We have received reports that Bitcoin withdrawals cannot be initiated due to an invalid bitcoin address error message that appears when attempting to withdraw Bitcoins. We have been investigating this and the causes for this problem are: 1) The high volume of small Bitcoin transactions. 2) One of the mining pools not working well recently. We are working on resolving this and we would like to apologize for any inconvenience caused. Thank you for your patience and your kind understanding in this matter.
