Bitcoin or Cryptocurrency in general are slowly been accepted and recognized by some financial institutions in some countries in the last few years. And there are well-known personalities that promotes the use of cryptocurrency around the globe.
But the questions is how come its value decreases after it has reached the highest in the last quarter of 2017. Was it being more accepted affected its value? What are your thoughts?
To bring price up there should be no sellers willing to sell at 5k range

Lets say if somebody would like to buy BTC on 20 Million usd , he could do that , but he possible will incrase price on that exchange and probably other sellers will follow that price and price will increase on other exchanges aswell . But usually big buys like 5 or even more Million usd happens on OTC ( OTC stands as over the counter )
