Union Investment, a $500 billion asset manager, is planning to add Bitcoin (BTC) to several investment funds as part of a targeted pilot program for its institutional clients, offering compelling evidence that crypto is becoming more mainstream in Europe's largest economy.  The Frankfurt-based institution told Bloomberg on Monday that it is considering adding BTC to a small number of investment funds that will only be available to private investors. For each fund, Bitcoin exposure will be limited to no more than 2% of total assets. Portfolio manager Daniel Bathe said the new investment strategy is likely to commence in the fourth quarter, though no fixed timetable was given. Union Investment is the investment arm of DZ Bank Group, an institution with over 800 cooperative banks. As of June 30, Union Investment had $507 billion in assets under management, making it one of Germany’s largest asset managers.
