Every one has a price in which they tend to buy Bitcoin. For me personally it is 12 K, if I see Bitcoin below that and have money I see it as a oppurtunity to buy. Though this is not backed by any research, this drives my strategy.

I thought if we could collect all such opinions, we could arrive at a price which everyone thinks as normal. Because if you think about it, all pur personal opinions of Bitcoin increase or decrease the price (Barring instance of manipulations by whales  which we can't do anything about)
