$ETH skyrocketed
Cryptocurrency, also known as digital currency, is a type of digital asset that uses blockchain technology for transactions and storage. Some popular cryptocurrencies today include Bitcoin, Ethereum, and Tether. Cryptocurrencies are not controlled by central banks, so their value fluctuates significantly with the market. Although they offer many attractive investment opportunities, cryptocurrencies also carry high risks, particularly regarding legality and security. Therefore, users need to understand clearly and exercise caution when participating in this market.
