Is this the end of Denarius? If yes , then this might be the last time i've invested in crypto's.
Already lost 200usd on Onix, 150usd on Briacoin and now 350usd on Denarius  
And now i'm also waiting for my first electric bill because of my day and night mining...
Is there any coin worth investing?
