in my opinion, this is what happening right now as the trend of bitcoin price has been sky rocketing. what do you think affects the price increase of bitcoin today?
Mostly speculation. People are buying bitcoins and expecting to make money when they sell at a higher price.
True, speculation is one of the biggest factors when it comes to how the price moves in the way it does, people are thinking that bitcoin is going to go up even more in the next year and if finally the lightning network is put to work then we are going to have the best scenario possible with bitcoin with a very high price and finally being able to manage many transactions per second.
