Allmost all Masternodes are sold, DEVs are still there, so why do you think it is scam?
Like Relarium, Radius, Nibex, Bitsolo... etc all cloned x11 coins with high roi, the devs at the start seems active but when have the money they run away and setup another coin and repeat the scam, all new users in bitcointalk... they arent devs are scammers copy pasters.
Take the presale money and kill the coin dumping it in graviex to deslisted, its the same pattern.
Now problems with explorer, wallet and more issues incoming.
go away from this shit scam coins, we must stop this.
There is a bot in graviex with those coins and that bot dump the coin with sales and volume, bid and ask are manipulated by that bot, you never get roi and it make you buy more mn thinking in take it.
