As the proud owner of a newly launched exchange I would say we all need time to prove ourselves.

If you want crypto currencies to stay decentralized, a lot of exchanges is a good thing.

From what I see a lot of coins have a hard time getting featured on one exchange and especially those who are not a simple copy/past of Bitcoin. For me, building a Mastercoin exchange was an opportunity to get into this business by providing a valuable service (liquidity) to an interesting approach for an alt coin.
Of course the volume is low: people don't know us yet and are carefull - and given the number of scams out there they should be. But I'm confident it will grow with time.
Of course I only propose one pair: I want to make sure everything works as intended before rushing into other alt coins.

As for "scam coins", I guess it's each individual's responsibility to do is own research to determine if a coin is valuable or not.
I'm not affiliated with the Mastercoin foundation but I'll tell you Mastercoin is far from a scam. It's been out there since August, has been announced weeks in advance, has many great features and is supported by a strong community. It's been traded almost exclusively OTC but with our live exchange things will soon be way different.

So my point is: Mastercoin should be featured here.

Perhaps a good thing would be to include the volume traded in the last 24h / 7days to have a simple metric to represent the activity of the coin?

earthcoin perhaps?

Thanks for removing nxt scam coin!

This. !

was something like this already suggested?
only include cryptocurrencies which are traded at least on "xx" number of long standing exchanges.
(and not if its only traded on 1-2 new shady "exchanges" with low volume which are created/selected solely for the purpose of market manipulation)

Why don't you look at the block chains and figure it out for yourself?

NXT has to be there! 

I may agree with you on this one. But I'm not sure.

Stats about the coin are wrong. It's not know how many coins are owned by the developer, and how many coins are actually in circulation (i.e how many has been 'mined' it's unknown). It does sound like a scam.

The developer is taking real money to give a coin he just made from air.

Premining doesn't make a coin a scam any more than allowing people with more money to purchase more mining power and get more coins as a result makes a coin a scam (this has been said more eloquently than I have on a previous page of this thread). Or consider Bitcoin and the fact almost no one was aware of it in 2009 -- does that make Bitcoin a scam? These arguments (and yours) have been made time and time again. It really is a good idea to read at least some of the thread before posting.

I would imagine a large percentage of CoinMarketCap.com users don't have the least bit of a clue what premining means or why/if it should matter and if they don't it probably won't be reflected in the prices of coins. I see plenty of successful coins on CoinMarketCap.com that had some premining or allocation of coins to investors or early adopters -- ultimately what we should care about is that our investments increase in value. Do you really care that a coin was premined if it's worth double next week what you paid this week? I sure wouldn't.

Thanks Gliss!
I use your site every day. I think its great.

My only recommendation (without reading previous posts, I'm sure it's been said) is to maybe make a "%" marker (or graph for coins like QRK) of how much each coin has been pre-mined. A lot of newbies are unaware of various scamcoins out there. 

Hey Gliss. So we are working on getting an ABE that works for Lottocoin at this time. Hopefully it will be ready soon and either one of the other guys
or I will send it to you the moment it's ready.

I will ask about getting a coin count that is as accurate as possible. Dogecoin and a few of the others generate random coins per block also so hopefully
we can just use whatever method they did.

Thanks!

btw, I'm having issues with the dgex.com API,  so if you see Nxt popping in and out, that's why.




Is there a link with the total supply count? It seems like each block generates a random number of coins, so I wouldn't be able to calculate it based on block height.

Alright.  I'm a little hesitant to put to up a coin with such low volume but I suppose I can average all of the prices for now until volume picks up.




If you click through on the price link you can see all of the exchanges on which it is traded.

Let's see:
the trade volume of Bitcoin might be something like 70 000 the last 24hours(0.5% of the total supply). That's not much, sure, because many people use it for long time storing or trading. Now there is coming Quark, which gets traded with 2000btc (5% of the the total supply), because it is so new and every one waits for the big dump or pump. -> it will get over proportional high listed at coinmarketcap.com. And you have the problem, that 20% of Bitcoin are owned by Satoshi and he might never spend it. So should the total supply be decreased?
-> I think, this is no good idea.



This was only with the new exchange "coinedup" an issue. When you make a sell order at 0.50$, you will sell at the best price which is $1.50, which will be the last traded price. All exchanges work like that. If not, this is a bug.

gamecoin on http://coinmarketcap.com/ now

because people (including me) are intrested in its price, scamcoin or not (not saying it is)

Why don't you remove NXT? It's a scam coin

Hi folks, this I initially posted as a separate topic but this thread perhaps a better place. With regards to some coinmarketcap shortcomings here I suggest possible ways to address them:

1. Market Cap is shown for all (pre-)mined coins, even if only a tiny percentage actually available for trading

-> e.g. for someone to push their newly designed coins to the top of the league, it would suffice to release a tiny percentage of them into the market, causing price squeezes due to shortage of supply. One could argue nothing wrong with that as the price is determined between market participants aware of supply shortages. However, the ranking in the league table vs coins with wide circulation is misplaced.

Suggestion -> supplement with a new ranking based on Traded Market Cap or a similar statistics (over a certain period across all available exchanges), e.g. Traded Market Cap (24h) = Traded Volume (24h) x Weighted (by volume) Average Traded Price (24h)


2. The prices on less liquid exchanges are sometimes "manipulated", in that off-market transactions for small volumes are enacted

-> e.g if the market with reasonable size bid / offer for a certain coin is at $1.50 / $1.55, someone might sell tiny amounts to lower bidders at $0.50 without risking much. Yet such transactions come on record and distort both price and market cap history charts.

Suggestion -> for each coin introduce some reasonable minimum treshold trade size which is required for inclusion of that trade into the price and market cap statistics.


3. The % change in Market Cap is shown over the 24h period, e.g. every minute we look at % change to a different reference point.

-> e.g. even though 24h change might be interesting, the observed % change is then not comparable to the observed % change value several minutes or hours ago. This is irritating and gets substantially magnified when prices are volatile, or being manipulated as per above.

Suggestion -> use % change to a fixed time point of a day, such as 0:00 GMT. Perhaps this has been already discussed, so apologies if the community already actually agreed on the existing format.

 

If you look back at my prior posts in this thread my main issue with NXT on coinmarketcap was that it is only on one exchange and that exchange only trades NXT/BTC. I also had the same issue with Dogecoin when it was only on coinedup.

One small market is not a very good representation of the value of a coin. In order for the market caps to reflect closer to true value you need an un-manipulated market and you need liquidity. It is far easier to fix the price on one market when you don't have to worry about arbitrage from other markets. Especially when the only exchange is owned by a stakeholder of NXT. It is just common sense.

The 100% minted to start and POS for fees is a side issue.

Maybe there is a compromise for this problem. Perhaps an astrix or notation disclosing that it is only traded on one proprietary exchange?

Kind of silly to compare coin values when all the other top 15 competitors are listed on at least 3 exchanges and those exchanges don't exclusively trade just one coin.
