At least Mikael Bouzaglo is still twittering ( https://twitter.com/mikael92764549 ), although not about Isracoin.
But who knows, maybe he used to get paid in ISR for his marketing and now it isn't worth it anymore
Isra web page has the last tweet from the same day he tweeted about ISR last.... I really have no idea what is going on.... sadly this really could have been country coin done right...But who knows, maybe he used to get paid in ISR for his marketing and now it isn't worth it anymore
