I also think the twitter account is fake and used by someone holding a lot of XDN to try pump the price and dump their holdings. I am sure by the end of next week nothing will happen leaving a lot of people dumping it.
How can be fake if the Twitter account is in coinmarketcap 
Maybe not fake but the way that account is tweeting stuff about XDN sounds a lot like those pump&dump groups that try to hype some shitcoins to dump their useless bags on the next fool. I still hold some XDN bought for like 10/15 sats and I really hope the dev come back with a huge stunt but I don't really see it happening...
