I read several articles on the internet regarding ethereum competitors. Some of them are quite reasonable competitors, but some or even many of them are just writing articles or promoting their latest projects.
In my personal opinion, there are several competitors to Ethereum that are currently quite competitive and sustainable. They are Binance Network with its BSC, Polygon (Matic), and currently Solana is also starting to be highly considered again because its performance is really growing. and indeed all three are considered enough to be alternatives to the Ethereum network, with speed and money security not much different, but with varied and more competitive fees, as well as affordable.
