There is a lot of cryptocurrencies with lower fees than Bitcoin and Ethereum, but they are not worth even close to what Bitcoin or Ethereum are, so people think they are not good for holding in wallet for long period of time.

When I started, Monero was the only alternative, but nowadays barely anyone mentions it anymore and Dogecoin has pretty much replaced it. Dogecoin has survived so far pretty much solely because of all the fuzz Elon Musk has created.
