Fiat makes more dollars simply by legislating, and then making ledger entries or printing dollars. Bitcoin can easily go the other direction. No more bitcoins can be made, but each of them can be divided into almost infinitely smaller segments of the satoshi. The satoshi, btw, is the smallest part of a bitcoin, currently, like a penny is the smallest part of a dollar. It is currently one 100-millionth of a bitcoin. But, all the devs need to do is change a little of the Bitcoin code to split the bitcoin as small as they want. For example. Let's imagine that there was only 1 bitcoin left in the whole world. That would mean there were only 100,000,000 satoshi's left in the whole world. But if you split each satoshi into 100,000,000 parts, suddenly there comes into being a whole lot more of this BTC token. Totally opposite of the way fiat has to work.
