I am not sure if that's the case: I think banks and government are starting to enjoying this new competition. If there is a room for new investment and new way to generate tax revenue, they two will go forward with Bitcoin. The adoption might take a couple years to mature but I am sure they are all looking at it (Congress is already planning to regulate bitcon at some point as a bill, and government agencies like FBI is targeting at deep web which is fueled by bitcoin now). I do however agree that bitcoin can't be a long term investment. Bitcoin is a short-term investment. You should buy and sell as soon as a target price is up.
