I've just notice that c-cex added coin named Goldmaxcoin
https://c-cex.com/?p=gmx-btc
http://www.gmxcoin.org/
This coin still don't have windows wallet or any links in their site

https://github.com/gmx16/goldmaxcoin-source
in github you can see the difference of what they announce and what they delivered

Code:

int64 static GetBlockValue(int nHeight, int64 nFees)
{
   int64 nSubsidy = 50 * COIN;

   if(nHeight == 1)
   {
   nSubsidy = 84000000 * COIN;
   }

   // Subsidy is cut in half every 840000 blocks
   nSubsidy >>= (nHeight / 840000);

   return nSubsidy + nFees;
}

static const int64 nTargetTimespan = 10 * 60;
static const int64 nTargetSpacing = 5 * 60;
static const int64 nInterval = nTargetTimespan / nTargetSpacing;

What is Goldmaxcoin?

Goldmaxcoin is a lite version of Bitcoin using scrypt as a proof-of-work algorithm.

2.5 minute block targets
subsidy halves in 840k blocks (~4 years)
~84 million total coins
The rest is the same as Bitcoin.

50 coins per block
2016 blocks to retarget difficulty

With block reward of 50 coins, target time of 5 minutes and halving every 840000 blocks how long will takes to the miner to mine coins equal to the premine of 84000000 coins?

It's very interesting why c-cex listed this shit
