Cocoa and chocolate industry
https://bitcointalk.org/index.php?topic=2871985.new#new has joined the ICO bandwagon . ICO has really brought all products and services to the blockchain technology. Banking, Eneregy, Farming and anything one can imagine in our daily live is been brought into online. Now we have cocoa harvesting also on blockchain to advance the production of chocolates and cocoa products.
Well everything can be a so called "blockchain project" but I think unless the project actually utilizes the blockchain to some degree in a way that makes their token have value, then I think their ICO is one to stay away from. This would not be something I would invest in when there are tons of projects right now that are going to revolutionize the way crypto works. Go for something more crypto related than just any old project trying to be crypto related......
As you said, there are projects right now that are going to revolutionize the way crypto works. Crypto ICOs mainly of the service and technology is not the only best ICO that is sustainable or profitable. There is a lot of great project in plantation that is making much profit for investors than other crypto related works. Hempcoin is one example of product base marijuana cultivation, its historical price chart has proven to be a sustainable coin over the past year than bitcoins and Ether combined.
