What is the idea here? Open a channel with each website that I visit. Lockup the BTC that I will ever send them but only send it to them slowly each time I visit it.
There is a contemporary books that explains this called The Impending Crisis of the South[1]. It was banned throughout the south and men were executed for distributing it in Arkansas.
Earth isn't really unique in terms of resources. It wouldn't really make sense to travel to another solar system just to get resource that you could obtain in your own. Even if they lack something in their own solar system, they could get it from other uninhabited solar systems without needing to trade locals. Ideas are what could be valuable in trade. If it is them visiting us rather than the other way around odds are they have more advanced technology than us so that isn't something they would need to trade. Our culture, what we sent on Voyaer, seems like it would be of the most interest to them. They might have entirely different senses than us (lacking sight, seeing different frequnecies, hearing different frequencies) that would make our "culture" something that wouldn't be enjoyed directly by them. Really as I see it, scientific interest is the one thing that would make them want to contact us.
I assume that any culture that is capable of developing interstellar flight will have a high degree of curiosity. We humans study even the most "mundane" life forms on our planet and try to study the rest of the universe outside of our planet. That is why I think extraterrestrials would want to make contact with us.
> We may be a phenomenon as uninteresting to them as ants are to us; after all, when we’re walking down the sidewalk we rarely if ever examine every ant along our path.
However, there are people who do study ants.
I think Roadside Picnic is a good novel but not indicative of how extraterrestrials who are capable of visiting Earth would actually behave.
