Twitter and other forums are full of Dogecoin fans and other Bitcoin skeptics slamming it for "energy inefficiency" and low throughput, saying other cryptos including Bitcoin Cash are so much better for payments that they're going to oust Bitcoin as the highest market cap cryptocurrency.
These arguments are fundamentally wrong. Paying for goods and services using any cryptocurrency is highly inconvenient compared to using almost any fiat gateway and requires meticulous accounting for tax calculations. Sure, you can automate the calculations but your data gathering has to be flawless. The whole idea is a non-starter.
Cryptocurrencies are digital property. There are few cryptocurrencies that have a value proposition that makes sense. Bitcoin has one owing to its adoption as an emerging store of value and a trustless settlement layer. There exist utility coins that are needed as payment for the use of blockchain resources such as Ether for the use of smart contracts on Ethereum or Hive for transactions on the Hive blockchain.
Bitcoin's energy inefficiency and low throughput are features, not bugs. The high energy use is a security measure and the low throughput helps keep the number of node operators high in order to decentralized the network.
