Instead, they just refresh their wallet apps, feeling richer by day while deferring consumption. Many of these burgeoning millionaires live like paupers. I've met many of them: all over the U.S., in Israel, in Brazil. They believe that every dollar they spend today is two dollars they won't make in a few months. Probably they are right.
There is nothing selfish, strange, or weird about holding an asset that is rising in value.
Bitcoin is undergoing a historic deflation, which simply means that its value is growing relative to the goods and services it can purchase. This is in contrast to inflation, in which the value of the currency falls relative to its purchasing power. Inflation inspires spending – better to get rid of the money while it is more valuable. Deflation inspires saving – better to keep it so that your wealth rises over time.
So there is nothing selfish, strange, or weird about holding an asset that is rising in value. It would be irrational to do otherwise. And there is nothing odd about spending like mad in an inflation either. Our expectations of the future determine what we do today in every life and especially in monetary economics.
