At first, I thought bitcoin was a useless and deceitful thing. Later, I thought it was a tool for speculation. Later, I thought it was a valuable invention.

Something of value must have a price. Now, the price of each BTC is about $9,000, which is much higher than the price it has shown for the first time: 10,000 bitcoins for a $15 pizza coupon. If I were the owner of the deal, I wouldn't have dared to eat pizza for the rest of my life.
What do you think is the future price of bitcoin?
