Sorry for a long discussion about the increasing supply of Bitcoin or any other currencies. I've read all of the replies and almost all of the terms used are beyond my knowledge about Cryptocurrencies, I am expecting replies that in order to create or increase the supply is all about reprogramming the cryptography used, but it turns out that there is something to do with genesis blockchain, the creator and the people using Bitcoins.

By the way, some said that an increase of supply will devalue Bitcoin, how?
