Portability in digital currency refers to the ease with which value can be transferred across borders and distances without the need for intermediaries. This makes digital currencies like Bitcoin a highly portable form of wealth that can be sent and received anywhere in the world, at any time.

The blockchain technology underlying digital currencies enables seamless, secure, and cost-effective transfers of value. For example, a billion-dollar Bitcoin transaction can be processed with a fee of just $4, which is even cheaper on the lightning network. This compares favorably with traditional remittances, which are often slow and expensive, making them inaccessible to many people, particularly those in low- and middle-income countries.

The portability of digital currency offers new opportunities for the unbanked in the developing world to participate in the global economy and transfer wealth across borders without the need for intermediaries, breaking down financial barriers and increasing financial inclusion.
