In the  block explorer page, it says there are 11 064 135.18 ZCOINs now in circulation? Is that accurate? Is there any fakecoins mint by the last bug?

you mean still there are two wallets kept by gary?

i think u've just mistaken zcoin for zcash.  and you cannot explain why the devs finally found something wrong with the incorrect circulating volume.  the devs gave explanation to this comic entry level error as following link and they said:
https://zcoin.io/language/en/zcoins-zerocoin-bug-explained-in-detail/
"
How we discovered the bug
Slightly before midnight on February 16th GMT+0, during a check to analyze how widely used Zerocoin transactions were in Zcoin, we discovered that the total Zerocoin spend amounts did not tally with the number of mint transactions and the spend transactions far exceeded the number of mint transactions.
Upon further investigation, the dev team discovered that at block 11002, the serial number for the spend transaction had been reused which meant that someone was exploiting a single proof to generate multiple spends. If the code was working correctly, the duplicate serial numbers should have been rejected.

in which they said clearly the hacker forging issue can be found by some method, even though possibly the free chainz explorer could be wrong, there do be some method to check it out. but unfortunately the devs did nothing.

well, smart guy. is there any correct blockchain explorer without showing the wrong richlist? i find non.
someone has had found something wrong with the rich list last december and reported to the devs, the devs said---something wrong's with the blockchain explorer...
well, it's ok, the chainz's doing this zcoin explorer for help and for free, there's nothing to blame. and i just didn't get it when the devs found something went wrong with chainz explorer, why didn't they just build one official explorer themselves. until now, after we just paid half a million dollars for them, still there's nothing.
possiblly the devs are toooooooo busy, so spending some coins collected to recuit some new coders could be a much more feasible plan.

 

 still something wrong with the rich list on https://chainz.cryptoid.info/xzc/#!rich
there's no zcoin blockchain showing the real number of coins circulated. I think the devs should pay some collected coins to find some other coders to do this.

btc38's now ceased the deposit and withdrawal of xzc, and there's no offical notice when these will be reopened.
the  price difference between cryptopia and btc38 majorly comes from the liquidity problem of cryptopia, in which the price of xzc is now 0.001btc, however if you buy 100xzcs, the price will go up to 0.0019.
btc38 and bittrex shares the best liquidity of xzc-fiat or xzc-btc, by value, btc38 takes about 65%-80% of all xzc trading, while bittrex takes another 20%-30%.

I think it's better stop worrying about Chinese people. One of the angel investor is from China, who possibly promoted the coin listing on btc38.com, biggest chinese based crytocoin exchange, on which no new coins have been listed for a long time.
Whales have been buy up on btc38.com since last week, however someone kept on dumping on bittrex.com, and price on btc38 is higher than that of bittrex for quite a long time.
So, problem comes back to the solution of the incident, if the devs cannot provide some convincing solution, there will surely great damage to both the angel investers and the exchange traders.
We are expecting the devs can destroy some coins they collected from the miners.

ok, I'm not a miner, always not.
I got an rMBP, but it cannot mine any coins no matter its zcoin or zcash, so I'm planning to buy a computer with gtx1070 which also performance well mining zcash. If the mining's profitable, I can lower down the cost of the computer, isn't it, even thought possibly I won't mine zcoin at all. So I wanna figure it out the hashrate of zcoin first.
To zcoin, actually the major problem's the code itself, the dump's over. BTC38 holds 430k coins of all and price is rising.

how many zcoins can you dig every 24hours? and how much kwh does your computer consume?

It seems the suspicious coin forging's carrying on. Check block 21704 out.
Seems they are forging at the number of 40.** one time, and changing them into one anonymous 100coins out.

ok， I got you.
take a look at address:  aPfRPrp1JNSxM4ibQhcbKfR1b5Ai6iW9YJ  a5mKiMEh2f7pc8GgTYCJUcPQmPN8bAkSAq   , which are also quite wierd.
It's keeping sending coins at the number of 40.06 each transaction.
btc38.com ceased the deposit for somedays from 2/10/2017 or 2/11/2017, possibly because they just find something wrong then, but they just reopen the deposit two days later.

the btc38.com holds 155000coins in total as viewed on the chinese version website on 1/25/2017, and the number of coins goes up to 43000coins till now. Seems most of that increase comes from the hacker.

seems the 100coins are transaction, however the minting's still 50coins a block.
