I strongly appreciate the presence of this bitcoin paper currency. It provides a good sign for bitcoin to perform its function as a means of payment. This also becomes a breakthrough technological innovation that can bring bitcoin better known to the public at large. This also benefits the bitcoin because people's trust in bitcoin can return well again and many people choose bitcoin for transactions and investments. That’s a bit of my opinion about bitcoin banknotes. Hopefully, bitcoin banknotes is soon realized and socialized well.
