Well, they are infinitely divisible in principle, so it doesn't matter too much.

(At the moment, there's a smallest fraction you can send on the network, but they can change that.)

Can't the change the 21M?

		Yes, they could change that, too. However I expect that adding more decimal places will actually happen, but adding extra bitcoins won't.

No they are not. There are only 8 decimal places, not infinite.

		AFAIK it can be changed later.
