think of limited supply as the opposite of what fiat has. you can't print bitcoin like you can print money without much of a limitation. but there is enough units in bitcoin to suffice usage.
secondly forks have nothing to do with bitcoin's supply. there already have been 2 hard forks directly from bitcoin with its blockchain. which one of them can you use as payment in your Microsoft account? that is right only bitcoin. not bitcoin x nor bitcoin y nor bitcoin z. only bitcoin. that means all those x and y and z are altcoins.
Yeah I know limited doesn't not enough, I meant limited as in a finite number of tokens. I do fully get what you mean about not being able to just make more of bitcoin as and when the developers want to, and I understand about BCH etc being altcoins my point was just that altcoins can be made from nothing essentially.
If the new chain does not gain a significant value, then the "supply increase" is irrelevant. Even if it does, users can choose to continue using the original chain (which has a maximum of 21 million coins) for as long as they like, and so the supply of the "original" BTC never increases at all.
I suppose you could more accurately say that the current Bitcoin chain will never have more than 21 million coins, and that it seems extremely unlikely that a new chain with a supply increase would garner any support.
Yeah like above, I get that its not BTC having it's volume increased, I think I worded my question wrongly, I mean more that the ability to make as many altcoins kind of seems flawed, am I missing sometihng about the way the fork create altcoins?
All I have to say is copy and past my textbook ...
'the medium is the message' (McLuhan, 1964)
Haha analogue to digital (sound signals) is actually something I understand a hell of a lot more about! I do undertand your point abou tthe McLuhan quote though.
