That's certainly true, mate. Ethereum is in high demand, so expect fees to go all the way to the moon. There's nothing we can do about this, other than wait for fees to decline or simply use an alternative blockchain network. Uniswap should rely on an off-chain scaling solution to lower costs and increase performance. Something like Optimism or Arbitrum should do the trick. Expect Uniswap to see a reduction in user base if fees continue to soar like there's no tomorrow.
One thing for sure is that ETH gas fees won't be high forever. The ETH 2.0 upgrade, Sharding and off-chain scaling solutions will make high fees and slow speeds a thing of the past. We just have to be patient in order to see great results in the future. With or without the high fees, Uniswap will be here to stay because of its decentralized and open source nature. Just my thoughts
