Exactly. What is more is that you can dig up more gold, you can make more metals, more commodities, more of anything of value,... except Bitcoin. You will NEVER be able to produce more than a very limited pre determined number of bitcoin (21 million), and as such it is not only immune from inflation, it's scarcity along with the increasing number of lost bitcoins compounds the situation, it will make it an ever INCREASING value asset, unlike almost anything else in the universe. The only thing that can go wrong for Bitcoin is if this characteristic can be in some way a negative, and I am struggling to see how that could happen.
Theoretically, there could be a trillion dollar bitcoin some day. As a matter of fact, given the nature of fiat money and Bitcoin, it is only a factor of time.
