Ethereum has been lagging behind when it comes to its price action, especially when it comes to its price action against BTC.
Several blockchains are faster and cheaper than Ethereum, and this is one of the key talking points for people who don't really like it.
They say that other networks, Sui and Solana for example, can do the same, but cheaper and faster.
This is not entirely wrong, but there are a couple of reasons why Ethereum might still be called king.
For example, Ethereum, unlike both Solana and Sui, has never experienced an outage, not even once.
