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.
It think its impossible for the etherium to die, because most of the projects now are in etherium base. Now that its value got higher than before and etherium is one of the best investments for a long term. As of now etherium is one of my best choice in choosing to invest my money and i have it in my wallet.
