Poloniex has decided not to list SuperCoin because of some disturbing things we turned up in our code review. I would like to draw your attention to this part of the ANN post:

Quote

- Total PoW coins will be 18.2 millions.
- Total coins (including PoS) will be about 50,000,000.

And these parts of the source code:

Code:

if (dAmount <= 0.0 || dAmount > 150000000.0)

Code:

static const int64_t MAX_MONEY = 150000000 * COIN;
static const int64_t POW_MAX_MONEY = 50000000 * COIN;

MAX_MONEY is pretty much what it sounds like. This means that the actual maximum supply of SuperCoin is 150 million, not 50 million. Furthermore, the maximum PoW coins is 50 million, rather than the claimed 18.2 million. The 150 million number appears twice in the code, so it can hardly be considered an accident.

We did not find evidence of an existing hidden premine, but extra coins could potentially be minted all at once at the end of the PoW phase, sent to exchanges via the "anon" feature, and dumped.

We have other concerns about the coin, particularly concerning the proposed method of anonymity, but the shenanigans with the maximum supply is sufficient for us to reject this coin.

Is this an amateur or a 10-years-old? The max coin limits the maximum coin, but does it mean the maximum coin will be generated?? Not at all. The generated coin depends on the formula in 3functions:
- GetProofOfWorkReward()
- GetProofOfStakeReward()
and
- GetProofOfWorkBonusRewardFactor()

These functions define how many coins will be generated. Moreover, even the system generates more coins than the MAX_MONEY defined above, there will be no problem at all, go look at the code. If Poloniex tech staff is that dumb, I feel very sorry for them, it is a joke!
