Yes we can manipulate the price of bitcoin using demand and supply which I believe is the so reason for the recent bitcoin price booming as a result of high demand for btc around the world
one of the biggest factors is due to halving day on July or 5 months ago, a lot of media preaching, including bloomberg. people who do not know be interested to know bitcoin, then they buy and use for the transaction. many of those who continue to be active users till now include me.
In 2013, 12 months after halving, the price rose about 50 times. This time might rise 10 times.
