Do cryptocurrencies 'bring anything useful for society'?

As a cryptocurrency and finance practitioner, I'm often asked the question: "Do cryptocurrencies actually bring anything useful for society?" It's a valid inquiry, considering the volatile nature and widespread skepticism surrounding digital assets. However, I believe the answer is a resounding yes. Cryptocurrencies provide a decentralized, secure, and transparent means of value exchange, cutting out traditional middlemen and offering financial inclusion to those who have been historically underserved. They enable cross-border transactions with minimal fees, providing opportunities for businesses and individuals alike. Additionally, blockchain technology, the underlying infrastructure of many cryptocurrencies, has the potential to revolutionize industries like supply chain management, healthcare, and voting systems. In short, while cryptocurrencies may be volatile, their potential to transform society is undeniable.
