i think the problem is simply that mining is no more profitable.. nowadays too many miners shut down their rigs, mining rig rental have always so many rigs available in x11 algo.. nowadays you can make real profit with ICOs or with POS coin with a great dev behind..
this coin was designed with a low block reward for one motivation: allow big earnings for ICO investors. The price was 500 sat, a price not sustainable by miners.. dev thought that price will would be decided by miners, in fact before launch so much people post here "this coin wil be at least at 1500-2000 sat" or even "at 5000 sat".. and i was agree...but this reasoning is truth only if price is really make by miners.. and this is not happening people, this is not happening because diff is always under 10..
so, i think until miners dont join this community, supporting it with their rigs, we can wait for ever even 1000 sat
