What types of money will not be used in the future?

In the future, physical cash, such as coins and paper currency, may become less common as digital payment methods gain prominence. Cryptocurrencies, while currently popular, may also face challenges in widespread adoption due to regulatory issues and volatility. Additionally, traditional banking systems might evolve or diminish in favor of decentralized finance (DeFi) solutions, making conventional bank-issued currencies less relevant. Ultimately, the future of money may lean heavily towards digital and programmable forms of currency.
