A cryptocurrency is a digital currency that is also fully decentralised. Decentralised means that this digital asset is not regulated or controlled by any central bank or any other financial institution. Based on the blockchain technology, cryptocurrencies ensure ultimate security, transparency and direct transactions. This means that one can send cryptocurrencies to another account directly without any intermediaries (i.e. banks).
Currently, apart from the cryptocurrency that started it all, Bitcoin, there are approximately a little less than 3000 cryptocurrencies.
A few of the most popular cryptocurrencies are Bitcoin, Ethereum, Cardano, Ripple, Stellar, and Dogecoin. Best cryptocurrencies to buy today, not necessarily the best, but a number of cryptocurrencies that the majority of traders have heard of include: Bitcoin (BTC), Ethereum (ETH), Cardano (ADA), Dogecoin (DOGE), and Ripple (XRP)
