Does cryptocurrency 'bring anything useful for society'?

Inquiring minds often ponder, does cryptocurrency truly "bring anything useful for society?" While some argue it's merely a speculative bubble, there are indeed several valuable contributions. Cryptocurrencies provide an alternative, decentralized form of payment, eliminating the need for third-party intermediaries. They empower individuals to conduct secure, anonymous transactions across borders, potentially revolutionizing international trade. Additionally, blockchain technology, the underlying framework of many cryptos, offers a transparent, immutable ledger for various applications, from supply chain management to voting systems. Cryptocurrency also acts as a hedge against inflation and economic instability, offering investors a diversified portfolio. However, the question remains: Are these benefits substantial enough to justify the hype and risks associated with crypto?
