And how can it get better than 82% when it's the percentage of coins there will ever be? Or are you saying the devs are constantly dumping their 82% premine?
Waaahaahaa, no they haven't, moronic fuckwit. Let's pretend that HitBTC isn't a scam with fake volume (I know, I know, but let's forget the bullshit for this) we can roughly calculate the total volume traded quite easily.
The (godawful) BCN website indicates that there are 184.47 billion BCN to be emitted. ChainRadar tells us the total coins emitted by March 12, 2014 (when BCN was "discovered", lol) as 147.95 billion BCN.
In order to find the total trade volume we use two JSON data sources: http://coinmarketcap.com/datapoints/bytecoin-bcn/volume/1403010113000/1438621454000/ (USD volume per day) and http://coinmarketcap.com/datapoints/bytecoin-bcn/price_usd/1403010113000/1438621454000/ (USD price per day) and divide the volume by the price to get the total BCN volume per day. Add this up and you get 119.05 billion BCN total volume.
So, shit heads, even if you were dumping your illicit stash 24 hours a day and nobody else ever bought and sold BCN you wouldn't have finished dumping the entire amount.
Liars, scammers, fucking asswipe scum need to learn that your scam isn't going to succeed. Give it up now.
