#XSuperApp Cryptocurrencies have revolutionized the digital economy. They are decentralized assets based on blockchain technology, meaning they do not rely on governments or central banks. Bitcoin was the pioneer, but today there are thousands of cryptos with different uses, from smart contracts to collectible tokens. Their value can fluctuate rapidly, representing both opportunities and risks. Cryptocurrencies allow for fast, global, and, in many cases, anonymous transactions. Additionally, they have opened doors to new forms of financing such as ICOs. Despite regulatory challenges, their adoption continues to grow. Some see them as the future of money; others, as a digital bubble.
