I asked what you did because I think the best thing anyone can do for Bitcoin is bring their expertise to the community and apply it. e.g. There are a lot of accounting problems for both individuals and companies holding Bitcoin given the regulations - you could write or do videos or create an excel program for Bitcoin accounting. That's just a random idea, but this is the thread I would pull on.

Define what "biggest bang" and "shortest period" practically mean for you and I can try to recommend something.
