The saga of embattled German fintech Wirecard has entered a predictable new phase; the digital payments company has filed for bankruptcy today due to “impending insolvency and over-indebtedness”; it is German regulators who are under fire now for failing to investigate the seemingly fraudulent activity; regulators have been trying to foster innovation and growth and even took steps to protect the company from its accusers – filing a criminal complaint and banning short selling of the stock; this is a major challenge for regulators who are trying to be innovation champions and enforcers at the same time.
