How many bitcoins will there eventually be?

Since bitcoins are being regularly rewarded to miners, will the number of bitcoins continue to grow indefinitely, or will there be a maximum total number of bitcoins in existence? And if there is some kind of limit, what is it and how is it…

Why was the upper limit of 21 million bitcoins put in place?

I am very new to this idea. My only knowledge of it is from the wikipedia page. It seems odd to me that there is an upper limit at all to the bitcoins that will be issued. Perhaps there is a simple explanation to this. Why was that limit set at 21…

Where is the number of Bitcoins limit specified?

Reading the original Nakamoto paper, I cannot see any discussion or reference to the upper bound on the number of bitcoins. Where is it specified that at most 21 million bitcoins will be minted?

At today's rate of progression when will the market cap of 21 million be reached? If bitcoin increases at such a rate. In addition to this, is it true that when the market cap is reached, miners will still get transaction fees? If so, how much will…

Does halving ever end?

Every certain number of blocks the reward is cut in half, for example from 50 to 25 BTC. Will this halving continue indefinitely, so the reward never gets to zero?

Does adding more miners create more bitcoin?

I was on another forum and the claim was made that the miners using new technology GPUs are flooding in and because of this there will be more bitcoin produced. My understanding of block rewards is it's like a horserace between miners (or group of…
