I am a long term supporter of Ethereum and know that it is the most trusted network to create smart contracts but the kind of Huge fees for withdrawal and swapping of tokens, we have to nowadays due to slow network or congestion , is going to make it unpopular coin in coming months and other networks like, Binance, EOS, Polka Dot may take its place . The issue with Ethereum is that its developers are trying to scale running Blockchain which is like repairing a car while driving.
I'm sure ethereum can last for at least 10 more years, the ethereum community is growing, look at the many ethereum-based projects that are worth up to billions of dollars and of course this makes ethereum even great.
The progress of this project will keep it alive, there are many developers who continue to support ETH chain not even there are many available option those developers stay and entrust their project using this system.
We wil continue to see more updates from this coin and possible to receive more rewards if you are one of those holders.
As long as there are people who still supporting this coin and the team still doing their job, expect that this asset will continue to live.
