There are no limits on how many tulips can be raised, given land and sunlight or even hydroponics. The creators of Bitcoin limited the total number able to be mined to about 22M.
Can you guarantee that the Bitcoin creators won't change their mind? I mean they could simply say, "Well since its so popular lets double that to 44 million so everyone can have a chance at getting a piece of the action..."
That is just it, they get “mined” which sounds like some weird video game. And limiting it to 22 million makes it a viable currency for a world of 7 billion, how?
I haven't been able to make up my mind about BitCoin, but there is no reason the algorithms couldn't be changed to allow for the production of more in the future. This is still a fiat currency.
The premise behind it -- mimicking the mining of gold -- is interesting and clever, but gold miners still have to invest in land, equipment, and labor to get more of it. "Mining" Bitcoins, though harder now, does not require the same risk-taking.
