So I'm playing around with a new ranking page that bases market cap on the available supply (available to the public), please check it out and let me know what you think.
http://coinmarketcap.com/available-supply.htmlCoins affected:
-AIRcoin (exclude 2500000 premine)
-Auroracoin (exclude 10500000 airdrop)
-Aphroditecoin (exclude 22500000 airdrop)
-Greececoin (exclude 16000000 airdrop)
-Marinecoin (exclude 9720000000 premine)
-Mastercoin (exclude 56316 reserved for developers)
-Ripple (number distributed as shown here:
https://www.ripplelabs.com/xrp-distribution/)
-SiliconValleyCoin (exclude 17500000 airdrop)
-SpainCoin (exclude 25000000 airdrop)
Any others that need to be adjusted?
I find it very interesting that you're changing it right before you add
SolarCoin. Would it be too shocking for the cryptocurrency community to see SLR debut at #3 on the list?
Heavily premined coins are just as legitimate as non-premined coins, if the organization that owns them is transparent about how it distributes them. SolarCoin, for example, will be distributed at a rate of 1 SLR per Megawatt-hour of documented and verified solar electricity generated. It's a currency that is actually
backed by something with real economic value -- and that's only possible because 99% of it is premined.
If you artificially adjust downward the market cap of a currency like this by excluding the premined coins, that doesn't provide an accurate picture of how much people value these assets. People who do their due diligence know if something is a premined or mostly premined currency, and its value is set by the free market based in part on that knowledge. If people thought the market cap should be less because of a premine, then the price would go down. The price and total value of the assets is what it is, regardless of anyone's philosophical views about what it "should" be.
I hope you will keep the default setting to show the
entire market cap, based on all coins that exist for a particular currency. That is the true market cap, factually speaking. Excluding the premined coins as if they "don't count" is just an opinion of some people. For the benefit of those people, sure, add filtering options where people can view the market caps without the premined coins. But please, keep the default list to show the real market cap, which includes all coins created. Premined coins are real assets with real value. In the case of SolarCoin, the organization that controls them has already started distributing them to solar energy producers.
Its pretty obvious where your interest lies in this (and your buddy who +1'd your post) -- to see Solarcoin rank high to get it pumped and dumped and sucker in the same fools who bought Aurora, Spain, Greece, etc etc and all the other scam coins.
But, actually, you're way off. If the coins aren't public tradeable, then they should not be included in the market cap. A TRUE market capitalization is literally the share price * the number of outstanding shares on the market. Pre-mined coins are not on the market, and as we've seen, over and over and over again, when they do hit the market, their value decreases (obviously) and the "market cap" decreases along with it. Including the pre-mined coins is utterly ridiculous and in no way representative of market capitalization, and given that's what this site purports to display, the default setting needs to be based on market supply.
It's not an "opinion" it's a fact of the financial markets. It's not a philosophical question, and you are simply wrong about what is factually the "real" market cap. Companies can't just issue extra shares without diluting their value. A market cap isn't based on theoretical value. We don't base bitcoin's market cap on the total number of coins that will eventual be mined, do we? Because they aren't on the market yet.
The more and more these scammy shitcoins (and I have no idea if Solarcoin fits into that as I've never heard of it, I am referring to the ones currently populating the top 20) keep jumping to the top before their inevitable decline to the bottom, the more this site loses credibility and someone else will become the go-to for checking market value.
For instance, for huobi I found
