We see sometimes bitcoin price increase or decrease. How I can predict whether bitcoin price increase or decrease.Again, who controll this price.I appreciate if you kindly share your experience.
The price is controlled by the market. Like a stock in a company except in this case it's a digital stock in a Limited Coin.
If it has market acceptance via businesses or peer-to-peer transactions then it has demand.
Supply > Demand the coin will not have value.
Demand > Supply = increase in token coin value
