An American CEO of a virtual currency exchange has been found dead in her home in Singapore.
A police spokesman said Thursday there was no suspicion of "foul play" in the death of 28-year-old Autumn Radtke.
The spokesman says Radtke was found dead in her home on Feb. 26.
Her company, First Meta, said it was "shocked and saddened by the tragic loss."
First Meta allowed users of virtual currencies such as bitcoin to trade and cash out the currencies.
The future of bitcoin has been under scrutiny since the collapse of the Mt. Gox exchange in Tokyo last month.
