Bitcoin is the future but paper money still have a lot of relevance now because population of people are yet to understand digital money. There has to be a wider coverage of the knowledge of crypto before it can dominate paper money.
True. Btc is the future currency. It may take several decades before it dominates the paper money because a lot people doesn't know what btc is. Several countries haven't informed yet about it, and it is not legalize in some other countries. Before it takes over, there should be a specific information about it, and I guess that it will take several decades before it takes over.
