BTC's circulating supply is now 19 billion out of the 21 billion caps.
Is it possible to calculate how much the price of BTC will go up until it hits the 21 billion cap?
I know there is some complicated math you can do about circulating supply, market cap, price etc, it's all connected,
How can I calculate the price potential of BTC within the next 1-10 years?
No it is not possible to calculate the price when the 21 billion cap is reached. The price might be the same, it might go up or it might drop. Supply doesn't always determine the price. There might be limited supply, but if there is no or less demand (that is no or less people are willing to buy bitcoin) for some reason, the price will be less. For some reason if bitcoin fails, then the price will drop to almost zero. If there were people that could find out the price, they would all be a billionaires by now.
