ECB concerned virtual currencies may not be sufficiently guaranteed

LUXEMBOURG (Reuters) - The European Central Bank is concerned about the use of virtual currencies because it is unclear who the issuer is and who guarantees them, ECB Executive Board member Yves Mersch said on Friday.

Bitcoin, the original and still the biggest cryptocurrency, has rallied nearly 75 percent in barely a month.

"We are concerned that this is private currency while we still think currencies have something to do with trust," Mersch told a conference in Luxembourg.
