Best DCA in 2024: Swan, River, Strike, Fold?

Looking at the recommendations in this sub, the most common options mentioned are Swan, River, and Strike.

Looking at btcpricetool.com it puts Fold as the cheapest option, but I never see it mentioned here?

I also see low fees with Gemini and Robinhood.

The plan is to move everything to cold storage eventually.

A lot of the advice is over a year old, so I'm curious if things have changed in that time. Has anybody done the work to compare the different options? Is something like Fold or Robinhood potentially better?
