Personally, I dont believe it. Still, there are some good projects in the crypto market. BNB is one of them, It's solving the high gas fee problem, But not yet can bet on Ethereum. So it is not about only the gas fee. Ethereum has a great blockchain system in the crypto industry. Still most of people using Ethereum smart contracts for creating new coins. For the long-term investment people buying Etehreum after Bitcoin.
Cardano is a good project, Recently it attracts most investors. So why pumping hardly, I also believe it will hit $5 soon. It's a good coin for long-term investment. But not think it's a competitor of Etehreum.
cardano was just being hyped but this wont long because Binance is only under 12 billion in capitalization things that can just be broken in a span of a week.
Binance is still the best competition against ethereum.
In terms of development and market, I think Binance is more suitable. Cardano is not bad but the use of market-developed technology and platform from binance is more supportive.
binance could become a giant on par with ethereum in the future.
