The fake 'LumoCash', listed on your exchange, gave a quick exitscam. Deleted Discord, Site and BitcoinTalk images. There is no longer any way to contact the developers, but Graviex remains firm in not delisting the fake scam. You can not trust an exchange like that. Who cares only about receiving money from fake projects and does not care about real projects.
