I think that with digitalization, paper money will soon be out of circulation. The development of digital payment methods, the development of the banking system and the emergence of cryptocurrencies prove this. In this period we are living in, digital fiat money is already widely used, but even though it is used digitally, it has inflation due to its fiat feature and is used physically. Cryptocurrencies have become inevitable for payment systems at this point.
Even the high commission fees charged by the banking system for international money transfers are an important reason to use cryptocurrencies. We can include bitcoin in payment systems, but for me, bitcoin is digital gold. Because btc is much closer to gold in terms of value retention and inflation protection. To realize a payment system that will be very common in the market, we will need usdt style coins. With the regulations that will take place in the crypto markets, crypto will be permanent for the payment system.
The goal is to reduce the cost by eliminating all the intermediaries that charge extra fees for their services. The idea was to promote the usefulness of the P2P trading system and the risk of using centralized authority for any financial movement. Paper cash is old-fashioned, and electronic currencies will take over the financial system one way or another. This can be done by CBDC or BTC but it is the future of our finances.
