Digital currency Bitcoin has been hit by another crisis after the CEO of an exchange was found dead at her home in Singapore in a suspected suicide.

Last week, two high profile exchanges and a bank dealing with the digital currency collapsed, leading many commentators to question the bitcoin’s future.

China, Thailand and Vietnam have all banned trading in bitcoin and other digital currencies.
Prior to her job with the exchange First Meta, Autumn Radtke worked for Apple’s cloud computing division.

Established in 2009, bitcoin has exploded in popularity due to the ability to transfer money directly between individuals without involving banks, credit card issuers or third parties.
