do you know what made the internet the internet we have today? The peripheral products
Sure. That doesn't mean that EVERY peripherial product has intrinsic value or not tremendously overvalued.
When I was a kid, there were ponzis, but people had to send 5 postcards to every person on a certain list under their names. Even worse, money ponzis had to be done in person, the horror!!!
Now we have the internet, so you just have to buy into my crypto ponzi, everything is much easier.

Why do people think chain letters could work?
The reason people are even tempted by these schemes is that the human mind does not have an intuitive view of geometrical progressions. Suppose we presume the chain letter to have a list of five people. You are asked to send one postcard to the person on top of the list, and remail the letter to five friends. You are promised thousands of postcards from all over the world if everyone participates. Your cost: a postcard, five photocopies and envelopes, and six stamps. Not much to risk to see what comes back...
