It would be helpful to also characterize Ethereum as not having been designed at the technical level to compete directly with Bitcoin.
While one can use ETH as currency, , and many do, the true value of the ETH blockchain lies in the inclusion of a "Turing complete" programming language which allows for the creation of "smart contracts" (coded conditions, instructions, triggers etc.) which are most useful in a business context.
Understanding that the scope of your article is not to provide a "look under the Ethereum hood" , perhaps my comment can add relevant perspective that explains why Ethereum should not be regarded as a direct BTC competitor, but still is.
All the best, and thanks for the article!
