I think Ethereum will lead the currency market in the near future. Ethereum is the second-largest crypto asset by market capitalization and is seen as a viable alternative to Bitcoin. It has a wide range of use cases and is backed by a strong development team. Ethereum's transactions are faster and cheaper than Bitcoin's and its smart contract technology offers a wide range of potential applications. Ethereum also has a larger total supply than Bitcoin, making it less scarce and thus more accessible to a larger group of users. It also has a more decentralized network structure than Bitcoin, making it more resistant to censorship and manipulation, Ethereum has the potential to become the leading cryptocurrency in the near future
I believe that ethereum will not "lead" crypto, as in be bigger than bitcoin, but it could definitely keep its spot, there is no returning back from that. I think it is easy to understand that bitcoin has this kind of vibe where it is the first thing ever, not just in the crypto world but even when a newbie comes in, they do not suddenly think about ethereum, they do not look at that, they look at bitcoin first and want to buy bitcoin first.
Look at the volumes, just that alone is a proof enough that bitcoin is bigger and will stay bigger because the difference is huge. I think it is important to keep their two rankings the same and keep it going for a while longer.
