I'm new here and don't know much about bitcointalk forums. But I thought about Bitcoin for a while. At one point I wondered what it would be like if Bitcoin was a physical currency instead of a digital currency. It would not have gained so much popularity, and its price would not have increased so much. If it were a physical currency, it would be very difficult to buy, how would you buy? And had to go to different stores to sell or buy. How difficult it would have been then. Are you thinking about this?
Bitcoin is a non-restrictive versatile currency that can exist both in physical and virtual/digital forms as long as its feature allows for this, and it can even be better & more secure than physical fiat currencies which also have electronic/digital Ledger like Bitcoin but in centralized form.
All you need to do to turn Bitcoin into physical currency and make it really easy to access is to print different denominations on physical materials like papers, with features that are hard to counterfeit imprinted on the materials,and then put them in circulation, probably in remote/isolated and autonomous areas without access to internet. When they need to, they can always exchange them electronically with bitcoiners in other places with internet for goods and services. This, combined with virtual uses, can add more value to Bitcoin and increase its price since more people without internet are creating more demand by using it in physical form.
