Why can only 21 million Bitcoin exist?
I've heard that there's a limit to the number of Bitcoins that can exist, which is 21 million. I'm curious about the reason behind this limitation. Why is it set to 21 million and not any other number? What's the logic or technology behind this decision?
How many BTC can ever exist?
I'm curious about the total possible supply of Bitcoin. I want to know how many BTC can ever be mined or exist in circulation. Is there a limit to the number of BTC that can ever exist?
