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 am also a fan of ETH. I think ETH is a pretty good coin for future investment. It's just that the drawback is a large fee as you say. I think ETH will be more advanced for the next few years. And also a lot of coins that use the ETH network.
