The price really depends on the behavior of the buyer and the seller, this is how we determined demand and supply affect also the price of bitcoin. In the future, the price of bitcoin will surely go even higher since the demand for this is continue to increase.
Yes, I agree the price is determined by the number of Bitcoin supply and demand. If more and more demand price Bitcoin will continue to rise and vice versa. Best wishes and I hope there are still many people who need Bitcoin.
