What makes people think that institutional money is going to change everything?

Aren't they smart enough to buy coins Over The Counter. In that case, price is not going to make moves. Also, they are not going to use it as a product/Currency, instead they will buy and hold as an investment. The only advantage i could see is, involvement of institutions will make taxing law easy. Other than that, mass adoption and increased usage is going to make massive price movement.

If people think that change in tax laws in developed countries could make mass adoption of businesses which will reflect in price, i agree. However, most people are in an assumption that, when institutions start buying, Market will explode.
