In fact, gold is an object that can be touched and felt but in the world of digital economy the flagship is bitcoin and its potential is much greater than that of any other currency or human precious metal !
The physical nature of gold makes it hugely inefficient for global transactions. And this is why bitcoin is important! It is the first currency in the world that is both decentralized and digital. It is more reliably scarce than gold and more private and transactionally efficient than "modern" digital banking. This is why people are excited about bitcoin, it has the potential to be completely revolutionize money.
