So presearch is a decentralized search engine, which rewards users and sponsors for using the platform. The UI of it is pretty sweet imo, as you can choose what search engine you want to search off of, including google. You can also create a toolbar of favorite engines for fast pickings.
Here's a link to their white paper - https://www.presearch.io/uploads/WhitePaper.pdf
As well as a link to their website - https://www.presearch.org/
They support chrome/firefox extentions which is pretty cool to.
So the tokenomics for this airdrop are basically, you get a free 25 coins for registering via a referral link ( I will provide mine, of course :D). And you get a max of 8 per day by using their website to search the internet.
You get .25 Presearch tokens per search, with the maximum payed searches being 32 per day.
During the bull market in January, presearch hit close to 1$ per token, so if you hodl these you're looking at potentially a 25$ airdrop as well as 8$ a day in token dividends(perhaps more if this takes off, only 250mil circulating supply) - all for doing something you probably would be doing anyway.
Anyway, hope you enjoy the airdrop and like the platform as well. MY referral link is here:
