What is Presearch
According to their website, Presearch is a "decentralized search engine to search privately and receive better results powered by blockchain technology". Basically, they pay you 0.12 PRE (their token) per search and it's a feature that goes well in hand with Brave's BAT and the Swash extension, the holy trinity of free long-term crypto.
How to use Presearch with Brave
It's very easy to set Presearch as the default search engine on a PC, you just need to install the extension or visit brave://settings/ and change it in the search engine section, but when we try to do it on Brave mobile we discover that there is a limited list of options and no way to add one!
By reading the community forum, we discover that to add a search engine to the list you just need to visit it, but doing so still isn't helping. The solution is to go on https://engine.presearch.org/ instead of just presearch.org and search for something, now the new option will appear on the settings page.
