What I consider the biggest threat to #bitcoin is the social threat to Bitcoiners. In Weimar Germany, or because of the hyperinflation then, jews were blamed for being wealthy in a financially difficult time. (Read When money dies by A. Fergusson) Even though this conclusion by the general population was wrong, it became a stigma nonetheless. We all know what happened next.

Blackrock choosing to incorporate bitcoin in their business strategy diminishes the social threat to Bitcoiners greatly, which is a perspective I haven't seen anyone consider yet.
