Interesting in themselves and worthy of attention are Singapore banknotes with a par value of 0.01 and 0.05 bitcoins. While it is difficult to imagine how these banknotes will go as a means of payment, but how they can be used as bonds. The organization that issued them should guarantee their redemption at par value in the case of presentation for payment. At the same time, bitcoin, as everyone expects, should increase substantially in price. This makes it possible to use them in this capacity, than simply as a payment method for mutual settlements.
We see that new forms of application of crypto-currency are being created, including their combination with conventional cash. This indicates that the crypto currency is still developing and the possibilities of its application are still enormous.
