That looks like an interesting concept. However as far as I understood there is no quaranties that they will buy back the shares eventually, is that correct? I checked https://mymue.com/Policys/LA and found nothing. It looks like you spend your 10`000 MUE to buy a licence for the masternode.
Also https://mymue.com/Policys/ToS is referencing to an old/inactive website (https://cryptxsoftware.mp-hosting.co.uk)
So if that website goes down what would happen to my MUE?
Honestly this is bad but I didnt read the TOS fully so I cannot answer your questions about it. But I do know that I could log in right now and sell a share of MUE and get 10k MUE for that. So yeah in essence your paying 10k MUE for a share of a MN but I dont know much beyond that at the moment.
