I like Duckduckgo, but I prefer Presearch as it is crypto backed and you can select Duckduckgo on their platform. Here is a link if you would like to join the Presearch beta: https://www.presearch.org/register?ref_id=111191

You can presently earn up to 8 PRE's per day at .25 PRE per search. It resets daily at 1800 CST.
