I have to a disagree a bit (no harm feelings for you pal, only my opinion). First of all, many large corporations have interest in cryptosphere due to the one and only thing - money. There is huge money in crypto, and companies are greedy. Second of all, with every year passing by, the legal reasons are being less problem for people who are looking in huge investments, due to some legalisation processes of crypto around the world (not everywhere of course, many countries in past years fully banned crypto too, unfortunately). "Huge investments in the cryptosphere are impossible" -> yes, there are, it's billions worth market and it's rapidly growing.

Talking about FTO they succesfully redeveloped their masternode system (via their newsroom: https://newsroom.futurocoin.com/become-a-masterode-owner/), to let their users have more influence on their future. It's kinda nice, but also interesting where it can take this project.

Going back to such sponorship deals - they aren't very harmful for large companies, someone gives you money, you give him a sign on their product. From economical side of view it's pretty simple. It gets more diffcult when it comes to the identity of a brand and organisations such brand wants to be associated, linked, related.
