Two cryptocurrency websites say Bulgaria's Fibank terminates contracts with them

"Fibank has terminated its relations with the exchange sites for cryptocurrencies in Bulgaria. The problem is not in Fibank, but in the banking system as a whole, and the bank's actions are quite understandable," Crypto.bg says in a statement on its website.

The operator of another cryptocurrency website, Cryptobank.bg, says that on December 7, the company has received an official confirmation from Fibank that the bank has terminated the contract with them.

Both operators say they are working to resolve the issue as they are unable to offer most or all of their services after the termination of the contracts.

Fibank officials were not immedately available to comment.

Fibank was Bulgaria's third largest bank by assets as of end-October 2017, according to central bank data.
