The high fees of gwei in Ethereum transactions are due to the supply and demand dynamics of the network. When the network is congested, users need to pay higher fees to prioritize their transactions. The popularity of DeFi and NFTs has increased demand for Ethereum transactions, leading to higher fees.
You can always use another altcoin depending on what you're using with that altcoin, there are a lot of alternatives like BNB, TRON, etc. which will have lower fees compared to Ethereum. If you insist on using Ethereum because have a special reason then wait until there are not many transactions in the Ethereum chain and you will see lower fees if that happens.
this only if the token is also deployed in other altcoin which majority are not, considering the fact that most of the token that's become popular are in ethereum, I doubt anyone would simply switch over blockchain.
