I recently started looking into ICOs that are connected to a real world economy. Mostly mining, but there are some other good once too.
My favorite so far:
https://www.hydrominer.org/ - here you basically buy an opportunity to mine through their equipment with their tokens
http://esonics.io/ - here you invest in a mining hardware production; this guys have a cool idea on how to re-finance their business thorough exchanging tokens for their products with a discount
Do you know any others?
You have taken it so light. Actually the case is, there are hundreds and thousands of the investment right now on planet earth in which you can get some amount as profit but the difference bitcoin made is just amazing. There is high profit ratio being provided by bitcoin and this one factor is heavy over all the others. So get into it, take a glimpse of it and try once.
