I think it all depends on the ethereum developer, if the developer is serious in developing then it looks like ethereum will never be defeated by other altcoins let alone lost in circulation. Most altcoins are lost because of not being serious in their development, but I see ethereum is an altcoin that will get better and will never disappear in the market. ethereum is the best altcoin
From what has been seen and proven, it is very clear that Ethereum is the best altcoin and has also gone through some very good development, including for the development of ETH 2.0 which many people are waiting for at the moment and it will take place tomorrow.
true to what you said, the development of ethereum which is currently underway is great and exciting news for ethereum users and holders. well, from that information, the ethereum developer has proven his seriousness in developing his product, namely ETH 2.0
