If you actually read the OP post, the requirements is not only sleep. The participant should also perform a significant amount of activity.
I went through them all, OP emphasized that the core of this monetization app is user sleep time.
Also, maybe you are not familiar but outside of the blockchain industry, there are actually some people that are being paid to sleep after doing certain activity.
This is nothing new, these are studies from real scientists.
Similar to this project, those people paid to sleep and then their physical data is collected to conduct some research. What I am trying to say is that the idea of collecting data from people sleeping is not new, but then combine it with the blockchain is something that I haven't heard, and it's definitely not only for lazy people.
You are believing that projects like this, they will collect physical data to conduct research or is it just marketing hype? The ultimate goal of these projects is profit nothing more, there will be no research, no technology here. They are also just looking to issue tokens and sell them for profit. And I also believe that if you participate in this project, your purpose is also to make a profit, not participate for the purpose of contributing to building the project.
