Yes, supply is getting lower we get that. If demand stays the same then the price will go up. That's econ 101. We are saying demand has to stay the same or increase for an increase in price. Demand is what comes first, not the supply. As others have said, you could have a coin with only 1 million supply, but that doesn't mean it will be worth anything. There has to be a demand for those one million coins. The demand for Bitcoin, however, has substantially decreased since December of 2017. If the demand keeps dropping then the price will too, therefore making the supply irrelevant because no one is fighting over buying coins. If the demand for Bitcoin keeps increasing and the supply keeps dropping then this will be good for Bitcoin. However, there is currently no reason for the demand for Bitcoin to increase.
