Why is it expected? I can go on and on. But if bitcoin is going to become mainstream, it needs to be embarrassed by Wall Street. If Wall Street is given the opportunity to invest in bitcion and does not (and to sustain a bear market, they simply cannot invest, even in relatively small amounts), then I would consider that a very bad sign for bitcoins adoption.
Reality can often be more banal than you expect. BOA report - real value - 1300.....A very conservative professional assessment...the kind that ensure you keep your job and that would have you hated on btctalk and reddit. But that's life, hopefully we'll see the heights, but nothing is certain and this may be a more muted affair than we expect.
I for one am more than satisfied with this journey so far, and plan to make the best of it moon or bust.
