> Is this still the case? Do folks day trade using DEXs for small amounts or are they still limited to longer-term trading due to the overhead?

I'd like an answer to this too.

I've been dollar cost averaging into BTC and ETH since the prices are low. But at the same time every exchange I see has fees that eat a large percentage. I know Coinbase allows you lower fees if you're trading big money each month, but I'm not doing that.
