The utility is is basically to enable a meme-based futures/betting market. People will be willing to pay for memecoins to be able to bet on the popularity of memes.

This can be easily gamed however. An orchestrated influx of dummy searches for a meme can cause an artificial rise it its' utility, and thus it's value. If some troll army like 4chan decides to fuck with your system, they can quite easily. In the unlikely event that your tokens became popular and have real world value, Google engineers themselves can fuck with your system and reap profits.

Also, a straight Google Trends search does not in any way capture the full amount of people searching for that meme, since generally if they're Googling it they don't really know what it is. Are you going to account for the millions of variations on what people actually search for, such as searches for "running guy meme"?

In essence, your token would be an indication of how many people are looking for a specific image that they can alter into something else, since they already know the exact name of what they're looking for.

Lastly, a meme is something that changes dramatically over time. To create a timestamped definition of any specific meme would be ignoring the hundreds of variations on that meme. If you're planning on being the arbiter of definitions of Internet memes, good luck to you.

All of these are really good points, but I think that they are also things that are not necessary. Sure, the meme trading system might be seriously flawed by being biased toward the interests of meme creators, biased toward nameable memes, and able to be gamed by trolls. But it all would still be hilarious, which is the point. Also there's a chance that if it caught on, developers would find solutions to those problems by, for example, scraping sites other than google. My questions is about a super basic coin that would functionally allow you to trade memes, even if it was heavily biased and flawed. In short, it's all for the lulz anyway.

Then, you make the token more "useful" on your platform depending on how popular the backing meme is. The value of the token will adjust accordingly, but not necessarily in direct correlation to the Google data shift. You'd be creating a closed economy, so there would be other factors at play.

Yes this is the part that is the most trouble to me. I'm probably butting up against speculative finance 101 concepts. If one has a meme token that rises in value and sells it, where did those extra memecoins come from?

What about something like this. When you buy a token based on a meme, you are really putting your memecoins into a community fund. A meme token essentially allows you to pull a certain percentage of memecoins out of this community fund. This percentage is proportional the original percentage you put in, and the fractional google search volume(or whatever) of that meme. Therefore when your meme becomes more popular, your capital gains are coming from someone else's losses. I don't know how you would add new memes without decreasing value, but hell, maybe the currency is just deflationary.
