This weekly update tracks some of the largest cryptocurrencies by market share: bitcoin and ether. While both are considered to be high-risk when it comes to investing, the two have foundational differences that investors should know. We’ve also included XRP, as it was one of the largest cryptocurrencies when this series began. According to Wikipedia, a cryptocurrency is “a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.”
