It's difficult to name a large financial institution that hasn't had a fairly recent "embarrassment of behaviour discovery", be it assisting drug cartels with money laundering, manipulating the price of gold / metals, or just plain immorally giving massive debt to obvious deadbeats and repackaging it with a AAA rating. Yhe whole finance industry is a festering wound.

Cryptocurrency, by comparison, is a mosquito bite, but there's enough blood to have started attracting the real bad bacteria across from the traditional finance world.
