Hey, thanks for reaching out!
It’s true, I’m not doing a good job allowing my users to learn more. If you have feedback how I could improve that, I’m grateful to hear it!
Now, the TL;DR version is:
A few people have created stock tickers for data sets they’re selling on Ethereum. If you buy 1 stock, you can use their data set e.g. once. I was interested in investing in these data tokens but didn’t know which ones were the best. So I started ranking them by how much and how widely they’re traded.
Hope that explains it a bit. Happy to answer further questions!
