What's your opinion on this? Will Ethereum last forever? Or will it eventually die? Do you think it'll retain its place as the second-largest cryptocurrency by market cap for long? If not, why? Do competitors stand a chance against ETH? Your input will be greatly appreciated. Thank you.

Nothing last forever but for technology to continue it must evolve it cannot stay as it is a new technology within technology will continue to come and challenge the leading one if Ethereum stay as long as it can, they need to continue evolved and there should be new developers to take over we cannot expect Buterin to live forever and this world is not meant to be forever.
