Folks are already using bitcoin for international commerce and remittances where they were underserved by banks and services like Western Union or PayPal. Bitcoin only needs to be useful for one kind of transaction for it to be enormously valuable. Once it is useful for some class of transactions it will be more valuable for other kinds of transactions. This is a classic network effect. The particular kind of transaction where I am convinced it will take off is international commerce. There are lots of potential transactions that are simply not happening because of the hassles of moving money around between currencies and banking/government regimes. There are lots of other transactions happening that are slow and expensive for the same reason. So bitcoin is providing value there, both by making existing transactions cheaper and making other transactions possible. I'm specifically thinking of capital and labor in currently underserved markets that can now more easily be exchanged where they were not before. Then there are whole classes of transactions that bitcoin makes possible that were not possible before. For example, right now one could write a bot that receives and spends bitcoin to provide some service and not have to get any permission from a bank or government to do so. What kind of cool weird services are going to come from that?
