The Presearch token economy is based off the investors that buy the tokens. The price has fluctuated quite a bit in the time I have used the platform. It was up fairly well when I started then when more people started getting to the required threshold, 1k PRE tokens and 6 months (I think) of using it, they started cashing them out. That put a lot of downward pressure on it like Steem and I wasn’t sure if it would recover. It thankfully recovered and has since been a huge spike in price, I think it’s related to the keyword staking aspect.
Keyword staking is great for investors, it gives them directed traffic that’s open for others to see. You can see who’s got tokens staked for a word and how much they have staked. Large non crypto companies don’t share that information from what I’ve read. You never know who else is competing and how much they are paying to compete.
